2) The next generation mid/far-IR space missions – formulating a European perspective | Paris | 9–11 February 2022
Mid/far-IR observations are crucial for addressing fundamental
questions in astrophysics and (exo)planetary science, as they can
uniquely unveil dust-obscured astrophysical phenomena, the main cooling
mechanisms, ice composition, key atomic, ionic and molecular lines
(e.g., water) and quantify the dust emission. Only with mid/far-IR
observations can we fully answer many of the important astrophysical
questions such as:
What are the processes that control the formation of galaxies, their
clusters, stars and planetary systems? What are the physical conditions
for galaxy assembly from the dawn of time? How has the chemical
composition of the Universe evolved from primordial gas to habitable
planets? What is the origin of the coevolution of galaxies and
supermassive black holes? What processes govern the different gas
phases in the ISM cycle? What is the role of the magnetic field in the
evolution of the ISM and in the star and planet-formation processes?
How does water trace the origin of our Solar System?
Over the past couple of decades, mid/far-IR space missions such as ISO,
Spitzer, Herschel and Planck have revealed the intricate, dust-obscured
interactions between stars and the interstellar medium of the Milky Way
and external galaxies at all redshifts. These missions proved to be
instrumental in refining our understanding of star formation as a
function of cosmic time and of the role of AGNs in galaxy
evolution. Ground-based and airborne submm/far-IR facilities, notably
ALMA, IRAM and SOFIA, have continuously supported these
quests. However, while the near-IR (< 5μm) and submm (> 800μm)
wavelength ranges remain very well covered by these modern facilities
and those to come on-line soon (JWST, ELT), we now need to discuss,
define and propose the next generation of satellite missions in the
mid/far-IR wavelength ranges.
Recognising the enormous progress that can be achieved using the
mid/far-IR domain, initiatives like SPICA and the Origins Space
Telescope were proposed. Unfortunately, neither of these will reach
fruition as conceived, leaving a large void in our coverage of the
electromagnetic spectrum for the coming decade. Indeed, both ESA’s
Voyage 2050 and NASA’s Decadal Survey reports recognize the uniqueness
of, and the need for, mid/far-IR probes to tackle the big questions in
the cold and obscured universe. In this context, it is imperative to
start planning the mid/far-IR space missions of the future in a timely
manner, to be fully prepared for when the agencies issue their next
mission opportunity calls.
The goal of this first workshop is to initiate and facilitate a
coordinated approach by bringing together the mid/far-IR community to
discuss the ‘big scientific questions’ that Europe would like to
address with mid/far-IR space telescopes. Once the key quests have been
identified, the focus will be redirected towards developing these
science cases and morphing them into viable European and/or
international mission proposals. To achieve a truly joint view towards
the future, this process should involve the full breadth of the global
community interested in mid/far-IR space astrophysics.

4) 30 months post doc position: New concepts in THz gas spectroscopy and sensing | Dunkerque, France
Project Halogen (ie CH3X; OX and HX; XX being Cl, I or Br) gas are produced by numerous industries, oceans and several other bio systems. During the past decades, researchers demonstrated their major role in the atmosphere. They act on pollutants and particles through reactional cycles and are involved in the radiative forcing. They are major players of the Earth's energy budget and global warming. Still, today no technique exists able to measure these species at realistic concentration in real time. In this multidisciplinary internship, we propose to implement an innovative physical concept shown on figure 1: coupling of the molecular frequency comb of a halogen gas to the optical frequency comb of a Fabry-Perot cavity. This coupling will enhance the light matter interaction and consequently enable to detect extremely small concentrations of gas. We will probe this system using TeraHertz time domain spectroscopy (TDS) and a dedicated algorithm developed in the team to the study of gas by TDS in Lille and electronic sources in Dunkirk.
In this project, the candidate will have to: (i) implement the gas spectroscopy setups; (ii) perform the experiments on simple gases and evaluate the limitation of the setup, (iii) implement the resonant cavity in the setup, (iv) perform the experiments on gas mixtures and evaluate the performances of the new approach. The candidate will work in the collaboration between two teams of experienced researchers: the THz-Photonics group at IEMN Laboratory (https://photoniquethz.univ-lille.fr/en/), in Villeneuve d’Ascq (Lille) (18 months) and at LPCA in Dunkirk (12 months). The IEMN group has a long lasting experience in the conception and realization of THz optoelectronic devices and is fully equipped to carry out this project, including state of the art microwave and mm/sub-mm-wave electronic instrumentation, MIR and THz laser sources and detectors, and a THz TDS dedicated to gas spectroscopy. The Laboratory hosts a 1500m2 clean-room with state of the art growth and fabrication facilities. IEMN is located in Lille, the capital of French Flanders, a vibrant city close to the Belgian border at 50min by train from Paris-CDG airport.
The THz group of LPCA have significant experience in the development of THz instruments for high spectral resolution spectroscopy based onto electronic and optoelectronic conversions. The group has also developed skills in gas phase metrology applications from rotational lines in complex chemical mixtures and is deeply involved in ambitious spectroscopy studies from microwave to Far Infrared region at different level of resolution using electronic,
optoelectronic and synchrotron sources. The LPCA is located in Dunkirk a lovely seaside destination with 10 miles of white sandy beaches very well known for its history and for its carnaval!
We are looking for a spectroscopist holding a PhD in physics or a related field. Having one of the following skills would greatly increase the chance of success of any application:
Optical/spectroscopy experiments
Gas phase molecular spectroscopy
Coding (python) or algorithmic / optimization
Cité Scientifique, Avenue Poincaré - CS 60069
59652 Villeneuve d’Ascq Cedex
http://www.iemn.univ-lille1.fr
We strongly advise any potential candidate to contact us by email or elsewhere to begin the discussion before any formal application.
The position will be funded by two successive contracts (18 +12 months), corresponding to the stay in the two sites. There is a high probability of getting a 6 months extension for the second contract through an additional funding
scheme.
Key words: TeraHertz, Time domain spectroscopy, strong coupling, algorithmic

Scientific context and motivations
Atmospheric particles are complex physical objects presenting a wide range of sizes, a highly irregular
shape and a variety of chemical compositions, which prevent from quantifying their impact on the Earth’s
climate (IPCC, 2021). Indeed, for such complex-shaped particles, no analytical solution to the Maxwell’s
equations exists. To quantify the interaction of such complex systems with the electromagnetic field, as
is required for addressing climate issues, light scattering numerical simulations have then been exploited.
However, these numerical models rely on simplying assumptions, which should be carefully checked and
for that laboratory measurements are coveted. In this context, of prime importance is the physical
process of light backscattering from a fundamental point of view but also from an applicative point of
view, as future lidar satellite missions (Earth Care, ACCP) will be based on this physical process, as
underscored by CNES in France. However, it is only recently that light backscattering has been for the
first time observed in a controlled-laboratory experiment for an ensemble of particles embedded in
ambient air (Miffre et al., 2016). For the first time to our knowledge, a laboratory polarimeter has hence
been designed and operated to quantify light backscattering by atmospheric particles (Miffre et al., 2016,
2019). This Pi-polarimeter allows quantifying the spectral behavior of atmospheric particles while
retrieving the particles deviation from isotropy.
Work plan
The present call is centered on the spectral properties of atmospheric particles. Indeed, no aerosol
spectroscopic database exists as is the case with the HITRAN database for molecules. This work is aimed
at contributing to fill this gap by extending our unique laboratory approach to the IR spectral range, which
is key for aerosol identification (Burton et al., 2016). More precisely, fundamental laboratory intensive
work is required to develop the Pi-polarimeter in the IR spectral range and unambiguously retrieve the
spectral and polarimetric behavior of studied aerosol particles. Such unique laboratory measurements
will then be made available to a broad scientific community, in France and abroad through publications
and conferences.
Candidate profile
To carry out this research project, candidates must hold a PhD in spectroscopy or / and polarimetry.
Complementary skills in atmospheric physics will be appreciated but are not essential. This 12 months’
position will be located at the Institute of Light and Matter (iLM) under the supervision of A. Miffre from
the ATMOS research group. Candidates are encouraged to use the below contact information for
discussing in detail if this post-doctoral position may be interesting for them.

7) Research Expert in Exoplanet Modelling | KU Leuven and the Royal Observatory of Belgium
The Institute of Astronomy (IoA) of the Department of Physics and Astronomy of KU Leuven and the Royal Observatory of Belgium (ROB) seek a highly motivated and skilled research expert in the field of exoplanet modelling. This recruitment is embedded in the research profile "STELLA: Study of Terrestrial Exoplanets' (Prf2021022) within the FED-tWIN framework, the Programme of sustainable research cooperation between the Belgian federal scientific institutes and the universities. The position is a full-time position (50% at the IoA, 50% at the ROB with open-ended contracts). In particular, we are looking for an excellent recognised scientist who can bridge and strengthen the expertise domains at the IoA and the ROB in the field of numerical models simulating the evolution of exoplanetary atmospheres, surfaces, and interiors. The overall short-term objective for the FED-tWIN researcher is to advance our understanding of close-in rocky exoplanets by linking theoretical models for the planet interior and its evolution (expertise domain of the ROB) with exoplanet atmosphere models including complex chemistry (expertise of KU Leuven). The long-term ambition of this FED-tWIN research is to boost our knowledge of the conditions favorable for a planet to be habitable and for life to develop. These novel models simulating the evolution of the atmospheres, interiors and surfaces of planets over billions of years will be crucial for an optimal interpretation of the current and future exoplanet observations in terms of the highest possible accuracy.

a) Disks around evolved binaries: do they form second-generation planets? | Jacques Kluska (KU Leuven) | December 16th, 4PM
https://us02web.zoom.us/j/86219181494?pwd=RHUxWlNWMC9TSVpFbFpWMlBiM3Nadz09
Meeting ID: 862 1918 1494
Passcode: 2Wxpc8
Abstract: Most of the planets were formed around young stars. But can they also form around dying stars? The origin of the diversity and comple: ity of the detected exoplanetary systems stems from how they form in protoplanetary disks. These disks are intensively studied around young stars thanks to the high-angular resolution provided by the VLT or ALMA. However, similar disks are also found around evolved stars, namely post-AGB binaries, raising the exciting but yet unanswered possibility of second-generation planet formation around evolved stars.
We have now the possibility to probe this possibility using high angular resolution instruments. In this talk, I will show the latest results of an extensive observing campaign of these disks using infrared interferometry at the VLTI (PIONIER, GRAVITY, MATISSE) and an innovative image reconstruction technique to decipher the complex interferometric signal. These observations show that these disks share many similarities with protoplanetary disks around young stars.
Whether or not planet formation is possible at the end of stellar evolution, these disks enable us to test planet formation processes in a parameter space that is unmet around young stars (e.g., short disk lifetime, high stellar luminosity) and further constrain planet formation processes.

c) Predicted signatures of planet formation and orbital evolution in the emission of protoplanetary discs | Clément Baruteau | lundi 13 décembre à 16h
Résumé:
The classical picture of protoplanetary discs being smooth, continuous structures of gas and dust has been challenged by the growing number of spatially resolved observations. These observations tell us that rings, gaps, large-scale asymmetries like spirals or arcs are common features of the emission of protoplanetary discs, which are often interpreted as signatures of the presence of unseen planets. During this online seminar, I will present some of our recent work on how the formation and orbital evolution of planets can impact the dynamics and the emission of gas and dust in protoplanetary discs. In particular, I will discuss the possibility that a single giant planet may acquire a substantial eccentricity in its protoplanetary disc, and what observational signatures this mechanism predicts.

2) EGU2022 ABSTRACT SUBMISSION OPEN | 3-8 April 2022 | Vienna, Austria and Gather Online hybrid format
a) From the environment of the Earth to the environment of the Solar System
Co-organized by PS11.1, BG7, CL3.2, GM11, OS4 (https://meetingorganizer.copernicus.org/EGU22/session/42718)
Abstract submission deadline: 12 January 2022 13:00 CET
(Consideration for early career support: 1 December 2021)
Submit abstract https://meetingorganizer.copernicus.org/EGU22/session/42718
EGU 2022 will have a truly interdisciplinary session aiming to bring Earth scientists and planetary scientists from a variety of backgrounds together to discuss important issues facing our greater world. Addressing the advancements and the problems of the 21st century and the future of Earth and surroundings put heavy emphasis on Earth and planetary sciences which have had some but not enough interdisciplinary interactions at large scopes. We hope to gather those that have already been involved in Earth/planetary interdisciplinary work and those that have been dedicated to one field but are curious to learn new perspectives. Please join us to give latest updates, highlight critical concepts, share knowledge, and foster new ideas in this rare multi-program session!
(SESSION DESCRIPTION BELOW AND https://meetingorganizer.copernicus.org/EGU22/session/42718)
On Earth, we have seen consequential environmental problems in recent years, such as devastating floods, monstrous wildfires, and deadly health crisis. Though humans did not have the intention of affecting the whole planet with industrialization, our activities have shaped the Earth as new studies more confidently demonstrate human activity as one of the major contributing sources to these events.
Concurrently, advancing science and technology is allowing humans to significantly expand their presence beyond Earth with strong commitments by space agencies around the world to increase their efforts. This also raises issues. We have already seen concrete examples, such as defunct objects falling down to Earth. Some issues could arise soon, such as from utilizing lunar resources.
With this background, we invite geoscientists, environmental scientists, planetary scientists, engineers, and policy makers to think about the following question: What have we learned by studying the effect of human activities on Earth at planet scales, and knowing that, how will the advancing space programs impact the state of objects in the Solar System?
Suggested topics include but are not limited to; review of environmental problems on Earth with implications to other planetary bodies; overview of new missions and assessment of their footprints; analog studies; past climate on Earth and other planets; case studies of how geoscientists have hypothesized, designed experiments, measured, and assessed the impact of human activities on Earth. Field-based, remote sensing, experimental, modeling, and theoretical works are welcome.

The signature of planet migration in transit-timing variation
Résumé : Planetary systems containing two or more planets sometimes appear to exhibit resonant configurations, where the period ratio between the planets is close to the period ratio of two small integers. These configurations enhance dynamical interactions between the planets, which can be detected by variations in the time of transits of individual planets (the so-called TTVs). In addition, resonant configurations are commonly thought to be the result of convergent migration, a process by which young planets migrate in a gaseous discs at different speeds so that the outer planet "catches up" with the inner one and captures it in a resonance. In this talk, we will demonstrate what is the imprint of disc migration on the TTV signals that are observed today. We will focus on two systems, K2-24 and Trappist-1, and link their current architecture to their past history.
b) Probing Unique Regimes of Exoplanet Science with Interferometry at CHARA and VLTI | Tyler Gardner | 25 novembre 16h
https://us02web.zoom.us/j/86219181494?pwd=RHUxWlNWMC9TSVpFbFpWMlBiM3Nadz09
Meeting ID: 862 1918 1494
Passcode: 2Wxpc8
Abstract: Current detection limits struggle to find exoplanets around hot (A/B-type) stars. Searching for planets in this regime provides crucial information on how planet occurrence rate scales with stellar mass. We are carrying out an interferometric survey to discover au-regime giant planets via differential astrometry orbiting individual stars of sub-arcsecond binary systems. The combination of milli-arcsecond resolution with stable wavelength calibration provides precision at the few tens of micro-arcsecond level in short observations at CHARA/MIRCX and VLTI/GRAVITY. This allows us to detect the wobble of a star from orbiting companions down to a few Jupiter masses. I will present the status of our survey, including newly detected tertiary stellar companions. We show that we are beginning to probe down to planetary masses. I am also involved with efforts to measure the orbit-dependent spectra of "hot Jupiter"-type exoplanets with interferometry, which can place useful constraints on atmosphere circulation models. I will present our first promising candidate detection, along with prospects for the future of characterizing close-in exoplanets with this technique.
c) Processus volcaniques et géologiques herméens associés aux espèces volatiles | Océane Barraud | Jeudi 2 décembre, 14h
Lien Youtube: https://www.youtube.com/channel/UCzPLngWE_6JVuJ4szh8U-RQ
Résumé:
Les observations récentes de la mission MESSENGER (Mercury Surface, Space Environment Geochemistry and Ranging) ont permis de faire des découvertes surprenantes sur Mercure, soulevant de nouvelles questions sur la formation et l'évolution des planètes internes du Système solaire. Les modèles de formation planétaire prédisent un appauvrissement en éléments volatils et un enrichissement en éléments réfractaires à la distance héliocentrique de Mercure. Cependant, les observations de MESSENGER ont révélé que la surface de Mercure est riche en espèces volatiles, tels que le soufre et le carbone. Ma thèse traite des processus géologiques associés aux espèces volatiles à la surface de Mercure, dans le but de mieux contraindre leur nature, leur origine et l'inventaire de ces espèces.
Durant ma thèse, j’ai étudié en particulier le volcanisme explosif et des unités géologiques observées uniquement sur Mercure, appelées hollows et dont la formation est encore mal comprise. Pour ce faire, j’ai collaboré avec des chercheurs européens pour créer une base de données, à partir des observations du spectromètre visible et proche infrarouge MASCS (Mercury Atmospheric and Surface Composition Spectrometer) de MESSENGER, qui contient plus de 4,7 millions de spectres et 28 paramètres spectraux.
L'analyse spectrale que j’ai menée, à l'échelle de la planète, des dépôts pyroclastiques, qui sont les produits d'éruptions explosives, a permis de mesurer précisément la taille de ces dépôts et de déduire que leurs dimensions ont été sous-estimées dans de précédentes études. Ce résultat a de fortes implications sur le contenu en volatiles magmatiques de Mercure. De plus, j'ai démontré que le plus grand dépôt pyroclastique de Mercure a sûrement été mis en place par une éruption de type phréatomagmatique, résultant de l'interaction entre un magma et une couche en sous-surface riche en volatiles.
En outre, l'analyse spectrale des hollows m’a permis de montrer que les spectres en réflectance de ces petites dépressions géologiques diffèrent des autres spectres de Mercure (par exemple, des dépôts pyroclastiques). Les spectres des hollows présentent une courbure concave unique entre 300 et 600 nm, que j’ai étudiée en détail par la mesure du paramètre Curvature, défini pendant ma thèse. Ce paramètre spectral est probablement lié à la nature des espèces volatiles à l'origine de la formation des hollows. Par conséquent, j'ai effectué une comparaison avec des mesures de laboratoire et des modélisations spectrales pour mieux contraindre la composition des hollows. L'étude a révélé que des sulfures, tels que CaS, Na2S ou MgS, sont les meilleurs candidats pour reproduire les propriétés spectrales des hollows de Mercure.
Les dépôts pyroclastiques et les hollows seront des cibles intéressantes et importantes pour la mission BepiColombo, et en particulier pour la suite instrumentale SIMBIO-SYS.

1) Atelier sur la science du système solaire avec l’ELT - lundi 6 décembre 2021 - LAM, Marseille
https://atelier-elt.sciencesconf.org
L'ELT est actuellement en phase de construction et devrait être opérationnel en 2025. Trois instruments de première génération sont en cours de réalisation : MICADO, HARMONI, et METIS. Un quatrième instrument de première génération est en cours de définition : MAORY. La France est impliquée dans tous ces instruments, que ce soit sur le plan technique ou scientifique.
L’intérêt de la communauté française de planétologie pour l’ELT est grand, mais nous devons nous organiser pour maximiser le retour scientifique. L’objectif de cet atelier est donc d’échanger autour de la thématique de la science du système solaire avec l'ELT, afin d'informer, de coordonner, et de préparer au mieux notre communauté de planétologues à l’arrivée de l’ELT.
L’atelier aura lieu sur une journée, le lundi 6 décembre 2021 (9h30-17h), dans l'amphithéâtre du Laboratoire d’Astrophysique de Marseille (LAM).
Afin de respecter les règles sanitaires, l’atelier est limité à 30 places en présentiel, avec présentation obligatoire d'un pass sanitaire valide. Il sera possible de participer à l’atelier en visio, mais probablement plus difficile de suivre les discussions. Ces conditions sont susceptibles d'évoluer. Les présentations et les discussions se feront de préférence en français.

OBJECTIVES:
This series of Cosmic Dust meetings aims at finding a consensus among experts on the formation and evolution of cosmic dust: where it comes from and where it goes. The meeting is organized by dust freaks who are very enthusiastic not only to make the goal achievable but also to establish a dust community across every scientifically relevant discipline for the development of cosmic dust research. For this reason, the primary objective of the meeting is to bring together professionals who deal with cosmic dust as well as provide an opportunity for participants to develop interpersonal relationships and scientific interactions among themselves.
SCOPE:
All kinds of cosmic dust such as
• intergalactic dust
• circumnuclear dust
• interstellar dust
• protoplanetary disk dust
• debris disk dust
• cometary dust
• interplanetary dust
• circumplanetary dust
• stellar nebular condensates
• presolar grains
• micrometeorites
• meteoroids
• meteors
• regolith particles
• planetary aerosols
are the subject of discussion. The meeting is open for any aspects of dust research by means of different methods of studies (in-situ and laboratory measurements, astronomical observations, laboratory and numerical simulations, theoretical modeling, data analyses, etc.). Also welcome are papers on dust-related topics, for example:
• the formation of molecules and their reactions on and their desorption from the surface of a solid substance
• light scattering by non-spherical particles and particulate surfaces
• space missions and instrumentation for measurements of particulates

BRIEF HISTORY:
The Cosmic Dust meeting started in 2006 as a session called “Cosmic Dust” of the 3rd AOGS (Asia-Oceania Geoscience Society) annual meeting in Singapore. Dust freaks have kept on organizing the session at subsequent AOGS meetings in Korea (2008), India (2010), and Taiwan (2011). The Cosmic Dust series has been recognized as the most successful session of the AOGS Planetary Sciences Section. In 2012, the time was ripe to be free from organizing restrictions on the AOGS meeting. From that time on, the Cosmic Dust meeting is totally independent of any international conferences and professional associations. The past meetings on Cosmic Dust have been held in a relaxed and joyful atmosphere. So will be the coming one!
3) Laboratory Astrophysics : tracking the evolution of cosmic matter towards molecular complexity| Les Houches, France | 13-18 March 2022
We are pleased to announce that the pre-registration to the thematic school on « Laboratory Astrophysics : tracking the evolution of cosmic matter towards molecular complexity » is now opened.
First of all, please visit the following website and proceed to a pre-registration.
https://lab-astrophysic.sciencesconf.org
The school will take place at “Les Houches School of Physics”, located in the Chamonix valley of the French Alps in March 13-18 2022. This winter school is a PCMI-supported initiative and is addressed to a very broad audience, extending well beyond its own frontiers. It includes the fields of astrochemistry and planetary sciences.
This school focuses on advanced experimental and theoretical approaches used to produce, analyze and investigate the properties and the evolution of extraterrestrial analogs in the laboratory, and dedicated to improve our understanding of the origin and evolution of complex molecular matter observed in space, from dense molecular clouds up to the formation of new stars, planetary bodies and comets. The program will present a wide range of complementary and advanced methods allowing the production, analysis and investigation of properties and evolution of extraterrestrial analogs, that were developed in recent years in close connection to the most relevant astronomical observations. Emphasis will be put on the degree of chemical and/or structural complexity which can be achieved in the gas and solid phases and at their interface under space conditions. The methods used to characterize the physics of silicates and carbonaceous dust, and to investigate the formation/destruction processes of ices will be detailed. Techniques used to analyze matter from cometary and asteroid origins will also be presented. During the school, interactive sessions with invited teachers will be organized and all participants are encouraged to present their own work during poster sessions.

Résumé:
L’environnement de Mercure est composé d’ions lourds originaires de l’atmosphère non-collisionnelle de Mercure (l’exosphère). La distribution
spatiale des ions les plus abondants a été caractérisée par l’instrument « Fast Imaging Plasma Spectrometer (FIPS) » embarqué sur le satellite
MESSENGER. Ces observations donnent des densités qui peuvent différer jusqu'à trois ordre de grandeur par rapport aux prédictions passées.
Cette thèse de doctorat décrit l’application d’un nouveau modèle numérique pour décrire les ions planétaires autour de Mercure, le Latmos
IoniZed Exosphere Model (LIZE). LIZE est couplée à un modèle de l’exosphère (Exospheric Global Model; EGM) et un modèle magnétosphérique
hybride (Latmos Hybrid Simulation; LatHyS). J’ai tout d’abord utilisé LIZE pour décrire la distribution des densités des ions Na+, O+ et He+
telle que mesurée par FIPS entre le 23 mars 2011 et le 30 avril 2015. Nous avons pris en compte le champ de vue et la couverture en énergie de
FIPS et avons simulé la fonction de distribution des vitesses. Ensuite, nous avons démontré que la réponse des espèces planétaires ioniques à
un événement radiatif solaire intense était non-linéaire et dépendait des espèces ioniques, de l’énergie, de la position dans la magnétosphère
et de la position de la source de l’événement solaire à la surface du Soleil par rapport à Mercure. Le modèle LIZE permet une analyse originale
des données FIPS et fournira des informations importantes sur le contexte des mesures qui vont être faites par la sonde BepiColombo.

Abstract:
The Hermean environment contains heavy ions which have their origin in Mercury's collision-less atmosphere (exosphere). The spatial
distribution of the most abundant ion species has been characterized by the Fast Imaging Plasma Spectrometer (FIPS) on the MESSENGER
spacecraft. Previous models of the planetary ion density distribution in Mercury's magnetosphere produce Na+ densities which differ by
1-3 orders of magnitude from the FIPS observations. This thesis describes the application of a new ion density model, the Latmos IoniZed
Exosphere model (LIZE). LIZE is coupled to a model of the exosphere (the Exospheric Global Model; EGM) and a hybrid magnetosphere model
(Latmos Hybrid Simulation; LatHyS). I first use the LIZE model to reproduce the Na+-group, O+-group and He+ ion density distribution
observed by FIPS between 23 March 2011 to 30 April 2015. We account for the FIPS field-of-view and energy range, and also simulate the 3-D
ion phase space density distribution. I then use the time-dependent LIZE model to study the response of planetary ion species to a strong
solar flare event. We demonstrate that the response of the planetary ion population in Mercury's magnetosphere to the flare is non-linear
with respect to species, energy, location inside the magnetosphere and the location of the flare source region with respect to Mercury. The
LIZE model offers a new capability for the analysis of FIPS data and will provide needed context to the ion measurements which will be made
during the BepiColombo mission, which will be made from two different positions in space and by instruments with different spatial, temporal
and energy coverage.
