Planet formation bursts at the borders of the dead zone in 2D numerical simulations of circumstellar disks
W. Lyra, A. Johansen, A. Zsom +2
As accretion in protoplanetary disks is enabled by turbulent viscosity, the border between active and inactive (dead) zones constitutes a location where there is an abrupt change i…
Standing on the shoulders of giants: Trojan Earths and vortex trapping in low mass self-gravitating protoplanetary disks of gas and solids
W. Lyra, A. Johansen, H. Klahr +1
Centimeter and meter sized solid particles in protoplanetary disks are trapped within long lived high pressure regions, creating opportunities for collapse into planetesimals and p…
Global magnetohydrodynamical models of turbulence in protoplanetary disks I. A cylindrical potential on a Cartesian grid and transport of solids
W. Lyra, A. Johansen, H. Klahr +1
We present global 3D MHD simulations of disks of gas and solids, aiming at developing models that can be used to study various scenarios of planet formation and planet-disk interac…
Survival of the mm-cm size grain population observed in protoplanetary disks
F. Brauer, C. P. Dullemond, A. Johansen +3
Millimeter interferometry provides evidence for the presence of mm to cm size "pebbles" in the outer parts of disks around pre-main-sequence stars. The observations suggest that la…
