Planet Formation - What CoRoT tells us.
Günther Wuchterl


CoRoT provides a well-defined sample radii, masses and densities of short period planets for a range of host star masses. That allows comparative studies of planet formation with respect to the solar system and host star mass.

We present a statistical theory of planet formation and evolution that allows to determine how frequent planetary masses and radii are. It is built on a small number of physical assumptions related to the planetary equilibria in arbitrary but gravitationally stable nebulae and the strong planetesimal hypothesis but does not a-priori assume a core and thus combines core-driven and disk-driven planet formation models. A new high resolution survey of all planetary equilibria and their subsequent evolutions in F and G star orbits up to periods of 128 days is presented.

Results are then compared to CoRoT discoveries in the probabilistic mass-radius diagram and effects of simple observational bias-models are explored.

Finally the following case studies and their planet formation perspectives are presented: (1) CoRoT-2b and planetary ages; (2) CoRoT-3b, CoRoT-15b and the upper mass limit of planets; (3) CoRoT-18b and -21b and the mega-core-problem;(4) CoRoT-25b and the planetary phase-diagram; (5) CoRoT-Jupiters and the radius anomaly.
