A Neural Network Subgrid Model of the Early Stages of Planet Formation
Thomas Pfeil, Miles Cranmer, Shirley Ho +3
Planet formation is a multi-scale process in which the coagulation of -sized dust grains in protoplanetary disks is strongly influenced by the hydrodynamic processes o…
High Resolution Study of Planetesimal Formation by Gravitational Collapse of Pebble Clouds
Brooke Polak, Hubert Klahr
Planetary embryos are built through the collisional growth of 10-100 km sized objects called planetesimals, a formerly large population of objects, of which asteroids, comets and K…
Toward a Population Synthesis of Disks and Planets I. Evolution of Dust with Entrainment in Winds and Radiation Pressure
Remo Burn, Alexandre Emsenhuber, Jesse Weder +5
Millimeter astronomy provides valuable information on the birthplaces of planetary systems. In order to compare theoretical models with observations, the dust component has to be c…
No self-shadowing instability in 2D radiation-hydrodynamical models of irradiated protoplanetary disks
Julio David Melon Fuksman, Hubert Klahr
Theoretical models of protoplanetary disks including stellar irradiation often show a spontaneous amplification of scale height perturbations, produced by the enhanced absorption o…
RV-detected planets around M dwarfs: Challenges for core accretion models
Martin Schlecker, Remo Burn, Silvia Sabotta +7
Planet formation is sensitive to the conditions in protoplanetary disks, for which scaling laws as a function of stellar mass are known. We aim to test whether the observed populat…
Hydro-, Magnetohydro-, and Dust-Gas Dynamics of Protoplanetary Disks
G. Lesur, B. Ercolano, M. Flock +16
The building of planetary systems is controlled by the gas and dust dynamics of protoplanetary disks. While the gas is simultaneously accreted onto the central star and dissipated…
