Planet disk interaction and orbital evolution

Willy Kley (University of Tubingen)
Jeudi 11 Octobre - 11 h 00
Salle Manuel Forestini - IPAG

As planets form and grow within gaseous protoplanetary disks, the mutual gravitational interaction between the disk and planet leads to the exchange of angular momentum, and migration of the planet. I review the current understanding of disk-planet interactions, focussing in particular on physical processes that determine the speed and direction of migration. The role of Lindblad and corotation torques as a function of the disk properties will be discussed, as well as the evolution of eccentricities and inclinations. Finally, I address the question of how well global models of planetary formation that include planet-disk interaction are able to match observations of extrasolar planets.
