The last twenty years have witnessed an exceptionally fast development in the field of the extra solar planets. The known exoplanets, almost 4000 to date, already show how diverse the planets in our galaxy can be. While the detection of exoplanets is an important ongoing field of activity, the characterization of their atmosphere has just begun and it is developing very rapidly. A lot can be learnt from spectroscopic observations of an exoplanet atmosphere; the molecular composition of giant exoplanet atmospheres can trace the planet's formation and evolution; the atmosphere of rocky exoplanets can host biosignature gases. However, the observations are challenging because the signal is often embedded in instrumental and telescope systematic noise.
In the ExoplANETS_A project, we will develop novel data calibration and spectral extraction tools, as well as novel retrieval tools, based on 3D models of exoplanet atmospheres, to exploit archival data from ESA Space Science archives (HST) combined with NASA Space Archives (Spitzer, Kepler) and produce a homogeneous and reliable characterization of exoplanet atmospheres....
Playlist de 10 vidéos sur les exoplanètes, ces planètes hors du système solaire. Dédié au projet de recherche européen Exoplanets-A sur l'étude des atmosphères des exoplanètes. Soutenu par l'Université Paris-Saclay, par le programme H2020 de l'Union européenne et par le CEA.

The BSF is the backbone of the observatory, is the primary load carrying structure for launch, and holds the science instruments. Image Credit Northrop Grumman
