Evolution of extrasolar Planets
Willy Kley
University of Tubingen
(Germany)
The orbital evolution of embedded protoplanets is
driven by gravitational interaction between the disk and the planet.
New results on plametary migration, and the evolution of
eccentricity and inclination are presented.
The newly discovered resonant planetary systems
HD 128311 and HD 73526 display interesting dynamcal features.
We present alternative formation scenarios for these systems.
