1) Atelier sur la science du système solaire avec l’ELT - lundi 6 décembre 2021 - LAM, Marseille

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.

2) Cosmic Dust | Kitakyushu International Conference Center | 22-26 August, 2022


Kitakyushu International Conference Center
3-9-30 Asano, Kokurakita-ku, Kitakyushu-shi
Fukuoka 802-0001

Monday, August 22 – Friday, August 26, 2022

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.

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

This time the meeting will be held on the island of Kyushu for the first time, the third largest island of Japans' five main islands famous for world's most active volcanoes (https://www.jma.go.jp/en/volcano/map_6.html). Kitakyushu city is the gateway to the Kyushu island from the main land of Honshu, separated only by 650 m (https://www.city.kitakyushu.lg.jp). It is also known as one of the UNESCO World Heritage sites as Japan’s Meiji Industrial Revolution (https://whc.unesco.org/en/list/1484/gallery/&index=13&maxrows=12).

Please complete online meeting application at the CPS website in order to attend the meeting. The deadline for the application is May 8, 2022, 11:59 p.m. Japan Standard Time (UTC+09:00). Because the number of participants is limited to a maximum of 50, the online application does not guarantee admission to the meeting. Participants will be determined at the discretion of the SOC and all applicants will be notified of the admissions decision by May 31, 2022. Priority will be given to those who contribute oral or poster sessions and retain enthusiasm for discussions throughout the meeting. For further details, please visit the Cosmic Dust website.

The early bird rate of 10,000 JPY (ca. $100) is available for those who complete both admissions application and abstract submission by April 24, 2022. The registration fee for those who complete admissions application on and after April 25, 2022 is 15,000 JPY (ca. $150). While no payment is required at the time of admissions application and abstract submission, the registration fee should be paid once admittance is guaranteed. No matter what circumstances are specified, the registration fee will not be waived. The payment of the registration fee permits free admission to all scientific sessions, daily coffee breaks, a banquet, and an excursion.

The best poster award will be given to the most excellent content and presentation of a poster at the Cosmic Dust meeting, although higher priorities are given to posters by students and junior scientists. The award winner will be announced in the closing minutes of the meeting.

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.


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.

The organizing committee : Jean-Hugues Fillion, Ludovic Biennier, Grégoire Danger and Aude Simon

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.

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.
