Magnetically Driven Obliquity in Circumplanetary Disks and Twisted Bipolar-jet Formation

Raúl O. Chametla, Martin E. Pessah, F. Javier Sánchez-Salcedo +4

Circumplanetary disks (CPDs) regulate gas accretion onto forming giant planets and provide the environment in which their satellites may form. We use high-resolution, global three-…

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…

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…

Pebble-driven migration of low-mass planets in the 2D regime of pebble accretion

O. Chrenko, R. O. Chametla, F. S. Masset +2

<Context> Pebbles drifting past a disk-embedded low-mass planet develop asymmetries in their distribution and exert a substantial gravitational torque on the planet, thus modifying…

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…

The inner disk rim of HD 163296: linking radiative hydrostatic models with infrared interferometry

Ondřej Chrenko, Mario Flock, Takahiro Ueda +3

Previous studies of the protoplanetary disk HD 163296 revealed that the morphology of its sub-au infrared emission encompasses the terminal sublimation front of dust grains, referr…

Turbulent stress within dead zones and magnetic field dragging induced by Rossby vortices

Raúl O. Chametla, Ondrej Chrenko, Mauricio Reyes-Ruiz +1

By means of three dimensional resistive-magnetohydrodynamical models, we study the evolution of the so-called dead zones focused on the magnitude of the Reynolds and Maxwell stress…

Accreting luminous low-mass planets escape from migration traps at pressure bumps

O. Chrenko, R. O. Chametla

We investigate the migration of Mars- to super-Earth-sized planets in the vicinity of a pressure bump in a 3D radiative protoplanetary disc while accounting for the effect of accre…

On wave interference in planet migration: dead zone torques modified by active zone forcing

R. O. Chametla, O. Chrenko, W. Lyra +1

We investigate planetary migration in the dead zone of a protoplanetary disk where there are a set of spiral waves propagating inward due to the turbulence in the active zone and t…

Evolution of the eccentricity and inclination of low-mass planets subjected to thermal forces: a numerical study

S. Cornejo, F. S. Masset, R. O. Chametla +1

By means of three dimensional, high resolution hydrodynamical simulations we study the orbital evolution of weakly eccentric or inclined low-mass protoplanets embedded in gaseous d…

Estimating the depth of gaps opened by planets in eccentric orbit

F. J. Sanchez-Salcedo, R. O. Chametla, O. Chrenko

Planets can carve gaps in the surface density of protoplanetary discs. The formation of these gaps can reduce the corotation torques acting on the planets. In addition, gaps can ha…

Trapping (sub-)Neptunes similar to TOI-216b at the inner disk rim: Implications for the disk viscosity and the Neptunian desert

Ondřej Chrenko, Raúl O. Chametla, David Nesvorný +1

[Abridged] The occurrence rate of observed sub-Neptunes has a break at 0.1 au, which is often attributed to a migration trap at the inner rim of protoplanetary disks where a positi…
