Simulations of eccentric disks in close binary systems
Wilhelm Kley, John Papaloizou, Gordon Ogilvie
We study the development of finite eccentricity in accretion disks in close binary systems using a two-dimensional grid-based numerical scheme. We perform detailed parameter studie…
Migration of Protoplanets in Radiative Disks
Wilhelm Kley, Aurelien Crida
In isothermal disks the migration of protoplanets is directed inward. For small planetary masses the standard type-I migration rates are so fast that this may result in an unrealis…
Planet Formation in Binary Stars: The case of Gamma Cephei
Wilhelm Kley, Richard Nelson
Over 30 planetary systems have been discovered to reside in binary stars. For small separations gravitational perturbation of the secondary star has a strong influence on the plane…
Influence of an inner disc on the orbital evolution of massive planets migrating in resonance
A. Crida, Zs. Sándor, W. Kley
The formation of resonant pairs of planets in exoplanetary systems involves planetary migration in the protoplanetary disc. After a resonant capture, the subsequent migration in th…
Collisions between equal sized ice grain agglomerates
C. Schäfer, R. Speith, W. Kley
Following the recent insight in the material structure of comets, protoplanetesimals are assumed to have low densities and to be highly porous agglomerates. It is still unclear if…
Disk-Planet Interactions During Planet Formation
J. C. B. Papaloizou, R. P. Nelson, W. Kley +2
The discovery of close orbiting extrasolar giant planets led to extensive studies of disk planet interactions and the forms of migration that can result as a means of accounting fo…
