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…

Dust back-reaction on gas around planets modifies the cold thermal torque
Raúl O. Chametla, OndÅej 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…

Low-mass planets falling into gaps with cyclonic vortices
Raúl O. Chametla, F. J. Sánchez-Salcedo, Mauricio Reyes-Ruiz +2
We investigate the planetary migration of low-mass planets (, here is the Earth mass) in a gaseous disc containing a previously formed gap. We perf…
