3) EPSC 2020 | Grenade, Espagne | 27 septembre au 2 Octobre 2020

Chers collègues,

Nous vous invitons à soumettre vos contributions pour le prochain EPSC 2020 qui aura lieu à Grenade, en Espagne, du 27 septembre au 2 Octobre 2020 (, sous réserve que l’urgence liée au COVID-19 n’impacte la conférence.
Nous attirons plus particulièrement votre attention sur les sessions relatives aux exoplanètes, en particulier la session:

Exoplanet observations, modelling and experiments: Characterization of their atmospheres
The field of extrasolar planets is one of the most rapidly changing areas of astrophysics and planetary science. Ground-based surveys and dedicated space missions have already discovered more than 4000 planets with many more detections expected in the near future. A key challenge is now the characterisation of their atmospheres in order to answer to the questions: what are these worlds actually like and what processes govern their formation and evolution?

To answer these questions, a broad range of skills and expertise are required, stretching from Solar System science to statistical astrophysics, from ground-based observations to spacecraft measurements, and atmospheric/interior/orbital modelling. The numerous studies conducted in the past twenty years have unveiled a large diversity of atmospheres. The next generation of space and ground based facilities (e.g. E-ELT, JWST, and ARIEL) will characterise this multifarious population in stunning detail and challenge our current understanding. Both theoretical works and experimental measurements are required to prepare for such a change of scale.

This session will focus on the atmospheric characterisation of exoplanets and the conveners welcome any abstract related to this subject.

We would like to encourage all people interested in this topic to submit an abstract, in particular early career scientists. The abstract submission deadline is 13 May 2020, 13:00 CEST.

Sincerely yours,

Olivia Venot, Monika Lendl, Giuseppe Morello, Vivien Parmentier, Ingo Waldmann


Ice Giant System Science and Exploration
Conveners: David H. Atkinson, Sushil Atreya, Thibault Cavalié, Leigh Fletcher, Mark Hofstadter, Kathleen Mandt, Olivier Mousis

This session welcomes abstracts addressing all aspects of ice giant systems including (but not limited to) the internal structure of the ice giants, the composition, structure, and processes of and within ice giant atmospheres, and ice giant magnetospheres, satellites, and rings.  We also welcome interdisciplinary talks that emphasise the cross-cutting themes of ice giant exploration, including the relationship to exoplanetary science and the connections to heliophysical studies. The session will comprise a combination of solicited and contributed oral and poster presentations on new, continuing, and future studies of the ice giant systems and the connection of the ice giants to our current understanding of planetary origins, both in our solar system and around other stars. We welcome papers that
Address the current understanding of ice giant systems, including atmospheres, interiors, magnetospheres, rings, and satellites including Triton
Advance our understanding of the ice giant systems in preparation for future exploration, both remote sensing and in situ;
Discuss what the ice giants can tell us about solar system formation and evolution leading to a better understanding of the current structure of the solar system and its habitable zone as well as extrasolar systems;
Address outstanding science questions requiring future investigations including from spacecraft, remote sensing, theoretical, and laboratory work necessary to improve our knowledge of the ice giants and their relationship to the gas giants and the solar system
Present concepts for missions, instruments, and investigations to make appropriate and useful measurements of the ice giants and ice giant systems.
The call for abstracts is now open. For more information, please see

Abstract deadline: 13 May 2020, 13:00 CEST.

4) Cool stars, Stellar Systems, and the Sun 21st Conference -  Annulation

Dear Colleagues,
We regret to announce that the Cool Stars, Stellar Systems, and the Sun 21st Conference, originally planned to be held on June 22-26, 2020, in Toulouse, France, has to be postponed due to the current Covid-19 pandemic. The decision was discussed within the SOC and LOC, and agreed by all members of the organizing committees. We plan to reschedule CS21 in Summer 2021.

Preliminary dates (tbc) for CS21 would be 5-9 July 2021, at the same location in Toulouse, France. We foresee that the program that was designed for CS21 this year, including the planned invited talks and the scheduled splinter sessions, will still be largely relevant next year, unless other hot topics emerge till then. We will continue to provide updated information on the current CS21 website.

As chairs of the SOC and LOC, we would like to express our gratitude to all the members of the organizing committees, especially to the members of the LOC for the efforts they deployed in this uncertain context. We extend our thanks to the chairs of the proposed Splinter sessions, to the speakers who accepted our invitation for the plenary sessions, and to all of you who had registered for the conference.

Take care, and we hope to see you next year!

S. Brun, J. Bouvier, P. Petit

5) 2-Years Pos-Doc on Mars research at IAA/CSIC, Granada

We are offering a 2-year post-doc position to work in the exploitation of recent/on going remote sensing observations by the instruments NOMAD and ACS on board the latest European mission to Mars, the ESA+Roscosmos ExoMars Trace Gas Orbiter.

The contract and research will be formalized within the current project NOMADACS, funded by the Spanish Space Plan under grant PGC2018-101836-B-100 (MCIU/AEI/FEDER, EU), and led by Dr Miguel A. López-Valverde, at the Instituto de Astrofísica de Andalucía (IAA/CSIC), in Granada, Spain.

The research will be carried out at the IAA/CSIC, within the GAPT team ( , Grupo de Atmósferas Planetarias Terrestres, lead by Prof. Manuel López Puertas). The Instituto de Astrofísica de Andalucía ( is a leading research center in Astronomy of the Spanish National Research Council (CSIC), and owns the distinction "Center of Excellence in Research" of the Spanish Severo Ochoa Program.

The investigation involve the retrieval of lower and upper atmospheric abundances of H2O, CO, aerosols and othe rtrace species, including the search for hydrocarbons, sulfur and rare isotopes and species. The studies will initially focus on the limb observations (solar occultation) using a state-of-the-art retrieval suite recently adapted to Mars conditions. Nadir observations are also available and might be incorporated at a later phase. Comparisons with and validation of the latest generation of Martian Global Climate Models are also contemplated.

The selection process consists of two stages: assessment of merits and an interview.

To apply, please send 1 single PDF file with a cover letter indicating motivation and a CV with publication record and copy of your Doctorate degree to:
