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…
Multipolar magnetic configuration: a trace of post-mergers events in circumstellar disks around FS CMa Stars
A. Moranchel-Basurto, D. Kocakova, M. Cemeljic +3
Context: Observations suggest that magnetic fields of disk-bearing stars may have non-dipolar configurations. However, the influence of these configurations on magnetospheric accre…
Resurgence of CO in a warm bubble around accreting protoplanets and its observability
O. Chrenko, S. Casassus, R. O. Chametla
The cold outer regions of protoplanetary disks are expected to contain a midplane-centered layer where gas-phase CO molecules freeze out and their overall abundance is low. The lay…
Planetary waves can activate resonant drag instabilities in 3D dusty gaseous discs
Raúl O. Chametla, Yasuhiro Hasegawa, Gennaro D'Angelo
Resonant Drag Instabilities (RDIs) in protoplanetary discs are driven by the aerodynamic back-reaction of dust on gas and occur when the relative dust-gas motion resonate with a wa…
Dust-void evolution driven by turbulent dust flux can induce runaway migration of Earth-mass planets
R. O. Chametla, O. Chrenko, F. S. Masset +2
Torques from asymmetric dust structures (so-called dust-void and filamentary structures) formed around low-mass planets embedded in a non turbulent dust-gas disk can exceed the tor…
