Dead zones and extrasolar planetary properties.
MATSUMURA S. and PUDRITZ R.E.
Abstract (from CDS):
We find that the dead zone is a robust feature of the protostellar discs that is largely independent of their environment, typically stretching out to ∼15 au. We analyse the possible effects of dead zones on planet formation, migration and eccentricity evolution. We show that the gap-opening mass inside the dead zone is expected to be of the order of terrestrial and ice giant mass planets while that outside the dead zone is Jovian or super-Jovian mass planets, largely independent of the star-forming environment. We show that dead zones can significantly slow down both type I and type II planetary migration due to their lower viscosity. We also find that the growth of eccentricity of massive extrasolar planets is particularly favourable through the planet-disc interaction inside the dead zones due to the large gaps expected to be opened by planets.
