The Planetary Accretion Shock. III. Smoothing-free 2.5D simulations and calculation of H alpha emission
Gabriel-Dominique Marleau, Rolf Kuiper, William Béthune +1
Surveys have looked for H alpha emission from accreting gas giants but found very few objects. Analyses of the detections and non-detections have assumed that the entire gas flow f…
Gravitoturbulent dynamo in global simulations of gaseous disks
William Béthune, Henrik Latter
The turbulence driven by gravitational instabilities (GIs) can amplify magnetic fields in massive gaseous disks. This GI dynamo may appear in young circumstellar disks, whose weak…
Survival of planet-induced vortices in 2D disks
Thomas Rometsch, Alexandros Ziampras, Wilhelm Kley +1
Context: Several observations of protoplanetary disks display non-axisymmetric features, often interpreted as vortices. Numerical modeling has repeatedly shown that gap-opening pla…
Spiral structures in gravito-turbulent gaseous disks
W. Béthune, H. Latter, W. Kley
Gravitational instabilities can drive small-scale turbulence and large-scale spiral arms in massive gaseous disks under conditions of slow radiative cooling. These motions affect t…
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…
Electric heating and angular momentum transport in laminar models of protoplanetary disks
William Béthune, Henrik Latter
The vertical temperature structure of a protoplanetary disk bears on several processes relevant to planet formation, such as gas and dust grain chemistry, ice lines and convection.…
