Planetesimal gravitational collapse in a gaseous environment: Thermal and dynamic evolution
P. Segretain, H. Méheut, M. Moreira +3
Planetesimal formation models often invoke the gravitational collapse of pebble clouds to overcome various barriers to grain growth and propose processes to concentrate particles s…
Migration of Jupiter mass planets in low viscosity discs
E. Lega, R. P. Nelson, A. Morbidelli +7
Type-II migration of giant planets has a speed proportional to the disc's viscosity for values of the alpha viscosity parameter larger than 1.e-4 . At lower viscosities previous st…
Dynamical signatures of Rossby vortices in cavity-hosting disks
Clément Mathieu Tristan Robert, Héloïse Méheut, François Ménard
Context: Planets are formed amidst young circumstellar disks of gas and dust. The latter is traced by thermal radiation, where strong asymmetric clumps were observed in a handful o…
Toward a new paradigm for Type II migration
C. M. T Robert, A. Crida, E. Lega +2
Context. Giant planets open gaps in their protoplanetary and subsequently suffer so-called type II migration. Schematically, planets are thought to be tightly locked within their s…
