3) Atelier CNES « Exobiologie : des missions spatiales aux expériences de laboratoire » | 15 Novembre 2022 | CNES, Paris
« Le prochain Atelier CNES « Exobiologie : des missions spatiales aux expériences de laboratoire » aura lieu le 15 novembre 2022 salle de l’Espace, au CNES.
La Covid nous a empêchés de nous réunir depuis deux années pour notre atelier d’une journée au CNES portant sur les missions spatiales et l’Exobiologie.
Avec la même équipe (Fabien Borget, Grégoire Danger, Jean-Claude Guillemin et Yann Trolez) nous souhaitons organiser ce nouvel atelier le 15 novembre 2022. Il portera sur « Exobiologie : des missions spatiales aux expériences de laboratoire » et associera comme nous l’avions fait dans le passé des expériences de laboratoire associées à des missions spatiales ou à une meilleure compréhension de la chimie prébiotique. Les missions d’Hayabusa 2 (achevée) et Dragonfly (projet) seront particulièrement discutées. Etablir des relations entre les expérimentateurs de chimie, de spectroscopie et ceux qui se sont engagés dans l’analyse des résultats des missions spatiales ou des expériences effectuées à partir de la Terre nous semble toujours une démarche évidente pour globalement progresser dans la thématique.
Entre les interventions des temps de discussions sont aussi prévues autour d’un café ou sous la forme d’une petite table ronde.
L’inscription est gratuite mais obligatoire.
Nous espérons vous voir nombreux à cette réunion

4) Exoplanets 5 | 17-21 Juin 2024 | Leiden - Pays-Bas
This is an early pre-announcement of the next instalment of the Exoplanets Conference Series:
*** Exoplanets 5: Leiden, The Netherlands – June 17-21, 2024 ***
Watch our tongue-in-cheek trailer: https://www.youtube.com/watch?v=V_fJmyBPYfY
We are well aware of the impact large conferences have on the environment. However, we think that it is crucial as a global community to keep on meeting in person regularly. Therefore, make your visit to Leiden count as much as possible, in particular when you come from far. For this reason we have set the dates so early. Combine it with other meetings, work visits, or even holidays. Make it worth it!
More information will follow in due course.
Kind regards,
Ignas Snellen

8) Post-doctorate for analysis of IR observations of exoplanets and development of retrieval models | LISA, Créteil
To learn more about the fascinating new worlds of exoplanets, several space telescopes have been designed, such as the James Webb Space Telescope (JWST) and the Atmospheric Remote-sensing Infrared Exoplanet Large Survey (Ariel, launch in 2029). The broad wavelength coverage and high sensitivity of the instruments on these telescopes will allow us to extract much more information from their data than has been possible so far, leading to many breakthroughs. However, these breakthroughs will only be possible if the models used to interpret the high-resolution observations are robust and reliable. In particular, the infrared spectra of exoplanets are analysed using retrieval models to determine the characteristics of the exoplanet atmosphere, such as the thermal profile, and to constrain the abundances of the main molecules. Significant research has been carried out in recent years to reduce the biases associated with the interpretation of spectroscopic data and enormous progress has already been made to improve these models and to take into account different effects and processes influencing planetary spectra (clouds, geometry, chemical composition, etc.). In the framework of the ANR project "EXACT (EXoplanetary Atmospheric Chemistry at high Temperature)", we wish to continue the developments allowing to improve the representation of the chemical composition in the data inversion models, by taking into account the chemical disequilibrium. To this end, the candidate will participate in the coupling between a retrieval model (TauREx) and an atmospheric kinetics model (Venot+2020) in order to take into account the out-of-equilibrium chemical composition in the analysis of observations. This model will be used to analyse observations of exoplanets, in particular those of the JWST, but also to prepare future observations of the Ariel telescope. Depending on the candidate's interest in Artificial Intelligence, it will also be possible to explore the use of Machine Learning methods to improve the performance of the retrieval and chemical kinetics model(s).
The candidate will work closely with Dr. Olivia Venot and her national and international collaborators. The main tasks will be to
- Use/develop the retrieval model TauREx and the kinetic model
- Use the new CHON+PS chemical scheme in the retrieval model
- Analyse and interpret observations
- Participate in the development of new observation proposals.
- Write scientific papers and disseminate research results at conferences and seminars.
- Participate in meetings of the Ariel Scientific Consortium
The candidate should hold a PhD in astrophysics, atmospheric physics or chemistry, or in a related field of research, with a strong interest in astrophysics, in particular exoplanets. The candidate is expected to have:
- A good knowledge of, or experience with, retrieval models (ideally TauREx).
- Knowledge of, or experience with, atmospheric chemical kinetics models.
- Knowledge of, or experience with, the proposal and processing of observations would be an advantage.
- Good programming skills, especially in Python, and possibly Fortran 90.
- Good knowledge of English to work in an international environment.
- Ability to work collaboratively, yet independently, within a team.
This work takes place in the framework of the ANR project "EXACT" led by Dr Olivia Venot. The candidate will join the Exobiology and Astrochemistry group, whose main objectives are the search for molecular structures and the study of the various physico-chemical processes governing the chemical evolution of various planetary objects (exoplanets, comets, Mars, Titan...). They are internationally recognised as world-class experts in the field of planetary atmospheres, both from a theoretical and experimental modelling point of view. They are heavily involved in the analysis of observational data from ground-based facilities and space missions. This team of about twenty people is composed of several permanent researchers, PhD candidates and post-docs. The work will also be carried out within a network of international collaborations, in particular with University College London (UCL) for the study of exoplanet atmospheres and the development of the Ariel mission.
The Laboratoire Interuniversitaire des Systèmes Atmosphériques (LISA) is a joint research unit of the CNRS, the Université Paris-Est Créteil and the Université de Paris. It is part of the Observatoire des Sciences de l'Univers EFLUVE and of the IPSL Research Federation. It is located in Créteil, an important student city in the Paris region. The research laboratory is a leader in atmospheric modelling at the international level. Its main mission is to contribute to improving our knowledge of the functioning of terrestrial and planetary atmospheres in order to understand their past and predict their future evolution.

11) Enseigner la spectroscopie de masse
Chers collègues,
La Société Française de Spectrométrie de Masse (SFSM) est une société savante visant à promouvoir la spectrométrie de masse, son développement et ses applications dans les milieux académiques et industriels, ainsi que son enseignement.
La spectrométrie de masse est aujourd'hui omniprésente dans de nombreux domaines et son champ d'application ne cesse d'évoluer avec le développement constant de nouvelles techniques. Nous sommes convaincus que cette évolution doit se répercuter dans l'enseignement.
Dans le but d'amorcer une réflexion sur le sujet, la SFSM souhaite dans un premier temps faire un état des lieux des pratiques d'enseignement et des différentes approches de la pédagogie de la spectrométrie de masse en fonction du public visé et du niveau de diplôme.
Pour cela nous proposons à tous les enseignants de bonne volonté, membres ou non de la SFSM, de remplir un court questionnaire. Si vous êtes intéressés par cette initiative et que vous voulez nous rejoindreou faire des propositions, vous pouvez aussi nous écrire.
Nous vous invitons à diffuser ce questionnaire à tous vos collègues qui pourraient être intéressés.

a) Webinaire Volatile Transport and Climate Modeling on Triton | Tanguy Bertrand (LESIA) | Mardi 11 octobre, à 17h
Inscription obligatoire ici : https://neptuneodyssey.jhuapl.edu/Events/b) A year of near-IR spectroscopy on Mars with Perseverance/SuperCam | Lucia Mandon & Clément Royer (LESIA) | Lundi 10 octobre, à 16h
We developed a Volatile Transport Model (VTM) and a Global Climate Model (GCM) of Triton and tested its ability to simulate its volatile cycles of N2, CH4 and CO as well as the dynamics of its atmosphere. We will present results published in a recent paper (Bertrand et al., 2022) showing how the volatile cycles evolve over long-term and seasonal timescales for varying model parameters, and what scenarios allow for a best match of the available observations. We will also present results regarding the atmosphere dynamics of Triton. Finally, we will discuss the implications of these results and how future observations could help us better understand how Triton works

The Perseverance rover (Mars 2020 mission, NASA) landed in Jezero crater, Mars, the site of an ancient lake, on February 2021. The main science objectives of the mission are the characterization of past environments, the search for preserved biosignatures and the collection of samples to be returned to Earth by the MSR mission (Mars Sample Return). The payload of Perseverance includes the SuperCam instrument, which combines various remote-sensing techniques to investigate the elemental and mineralogical composition of rocks and soils. In particular, the near-infrared reflectance spectrometer (IRS), which covers the 1.3–2.6 µm range, allows for the identification of a wide variety of mineral phases, and especially hydrated ones.From a technical point of view, IRS is a miniaturized spectrometer based on AOTF (Acousto-Optic Tunable Filter) technology. This optical element is the cornerstone of the IRS' performance and its flight calibration will be presented in this seminar. Then, we will give an overview of the minerals detected by the IRS during the first year of the mission and the implications on the geological history of the crater floor in terms of igneous and alteration processes. As the IRS is the first near-infrared spectrometer operating directly on the surface of Mars, we will also discuss how these results bring insights into the orbital studies using near-infrared data.
