Exoplanet observations, modelling and experiments: Characterization of their atmospheres

Convener: Olivia Venot | Co-conveners: Monika Lendl, Ingo Waldmann, Martin Turbet, Giuseppe Morello

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 will have soon discovered 5000 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 the properties of these worlds 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.
Current as well as future ground and space based facilities (e.g. ESPRESSO, E-ELT, JWST, 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.
