3D Simulations of Type-I Migration in Nearly Laminar Disks

We report results from 3D hydrodynamic disk simulations with an embedded planet. We examine the planet’s migration dependence on the disk viscosity. We find that the Type I migration can be slowed down significantly in low viscosity disks. The density feedback effect that was studied in 2D simulations still exists in 3D disks and causes the slowing down of Type I. Future work will address further the quantitative differences between 3D and 2D in slowing down the migration.
