EXOA2

Characterizing the diversity of exoplanetary atmospheres
Conveners: Yassin Jaziri, Thomas Drant | Co-conveners: Olivia Venot, Martin Turbet

There is a great diversity of planets, and probably a larger diversity of atmospheres. Since a few years, we are entering a new era in the characterization of exoplanetary atmospheres, thanks in particular to the very high-quality observations of the JWST. In a very close future, these data will be supplemented by observations from space missions (e.g. Ariel) and ground observations (e.g. ELTs). There are several approaches to characterizing these atmospheres: observations, modeling and experiment. These three approaches are very complementary to each others, and it is important to see in each way they can be linked together.

This session aims to: (1) share recent results from the latest JWST observations on exoplanetary atmospheres and future observational strategies, (2) present results from the latest state-of-the-art atmospheric models and retrievals, and discuss future development needed, (3) highlight experimental results on atmospheric studies and their complementarity to models and observations, and (4) improve synergies between these different approaches.
