Characterizing exoplanets atmospheres with space photometry at optical wavelengths

Characterizing exoplanets atmospheres with space photometry at optical wavelengths

Space photometry such as performed by Kepler and CoRoT provides exoplanets radius and phase curves with an exquisite precision. The phase curve constrains the longitudinal variation of the albedo and shed light on the horizontal distribution of clouds. The planet radius constraints thermal evolution...
