Global simulations of accretion flows onto perturbers embedded in magnetized disks -I. MRI and jet formation in ideal MHD
Raúl O. Chametla, F. J. Sánchez-Salcedo, Martin E. Pessah +1
We present the highest resolution global MHD simulations to date of gas flow around a low mass a perturber with mass ratio , embedded in an accretion disk ar…

Turbulence destroys thermal lobes around Mars-sized planetary embryos
R. O. Chametla, A. Moranchel-Basurto, F. J. Sánchez-Salcedo
The release of heat by a planetary embryo modifies the local density perturbations, forming thermal lobes in its vicinity, and thereby altering the torque exerted by the disk on th…

Dust back-reaction on gas around planets modifies the cold thermal torque
Raúl O. Chametla, Ondřej Chrenko, F. J. Sánchez-Salcedo +7
A nascent planet in a gas disk experiences radial migration due to the different torques which act on it. It has recently been shown that the torques produced by the gas and dust d…
