Exoplanet observations, modelling and experiments: Characterization of their atmospheres
Convener: Olivia Venot | Co-conveners: Monika Lendl, Giuseppe Morello, Vivien Parmentier, Ingo Waldmann, Corentin Louis, Nicolas André

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, from ultra-hot Jupiters to temperate super-Earths. The next generation of space and ground based facilities, including current high-resolution instruments (e.g. ESPRESSO, Spirou, CHEOPS, IGRINS, 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.
