Irradiated disks and planet population synthesis

Recent planet population synthesis models (Alibert et al 2010, submitted) have emphasized the key role played by the proto-planetary disk properties in determining the overall planet population characteristics. We present a disk model that takes into account viscous heating and irradiation by a central star and compute the resulting disk structure. As a first step, we consider the case of an equilibrium flaring angle. We then compute the flaring self-consistenly and show that this results in self-shadowed area which affect the disk structure. We illustrate the consequences of the resulting changes in the disk structure on the planet population by comparing synthetic populations corresponding to each of the different structures.

Transiting exoplanets are crucial to understanding planetary formation and structure because they are the only ones we could determine mean density by measuring the radius and the mass using precise photometry and spectroscopy. CoRoT is the first space mission dedicated to find transiting exoplanets. From the first transiting brown dwarf to the first transiting rocky planet, CoRoT have already discovered many very interesting exoplanets. In 2010, the number of CoRoT transiting exoplanets will increase significatively with for example a temperature Jupiter in a 95-days period or a highly-eccentric hot-Jupiter. I will present theses new exoplanets discoveries.
