Planets in turbulent Disks
Planets form in protoplanetary accretion disks
around young protostars. These disks are driven by internal
turbulence and the gas flow is in general not laminar but has
stochastic components. For weakly ionized disks the turbulence
can be generated purely hydrodynamically through the vertical
shear instability (VSI). Planets, that are forming in such turbulent
disks, experience random components in the torques acting on
them, that will modify their migration behaviour.
In this contribution we present results of our study of the
impact that a turbulent disk has on an embedded planet. For
that purpose we performed three-dimensional hydrodynamical
simulations of a locally isothermal disk with embedded planets
of various masses. For the lower mass planets (5 and 10 M )
we find that the inward migration rate can be faster than in the
laminar case, while for the more massive planets (30 and 100
M ) the results agree well with the laminar results
Proceedings of the 4th bwHPC Symposium
The bwHPC Symposium 2017 took place on October 4th, 2017, Alte Aula, Tübingen. It focused on the presentation of scientific computing projects as well as on the progress and the success stories of the bwHPC realization concept. The event offered a unique opportunity to engage in an active dialogue between scientific users, operators of bwHPC sites, and the bwHPC support team
