In circumstellar disks around young stars, the gravitational influence of nascent planets
produces telltale patterns in density, temperature, and kinematics. To better understand …

Context. Planets with masses larger than about 0.1 M⊕ undergo rapid inward migration
(type I migration) in a standard protoplanetary disk. Recent magnetohydrodynamical …

Using linear perturbation theory, we investigate the torque exerted on a low-mass planet
embedded in a gaseous protoplanetary disc with finite thermal diffusivity. When the planet …

We performed linear calculations to determine the Type I planetary migration rate for 3D
locally isothermal disks with radial temperature gradients. For 3D disks with radial …

Circumplanetary disks (CPDs) may be essential to the formation of planets, regulating their
spin and accretion evolution. We perform a series of 3D hydrodynamics simulations in both …

The migration of planets on nearly circular, non-inclined orbits in protoplanetary discs is
entirely described by the disc's torque. This torque is a complex function of the disc …

Context. Type-II migration of giant planets has a speed proportional to the disc's viscosity for
values of the α viscosity parameter larger than 10− 4. Previous studies based on two …

We present simulations of low-mass planet–disc interactions in inviscid three-dimensional
discs. We show that a wind-driven laminar accretion flow through the surface layers of the …

The wide, deep cavities of transition disks are often believed to have been hollowed out by
nascent planetary systems. PDS 70, a∼ 5 Myr old transition disk system in which a multi …

We study the evolution of the eccentricity and inclination of protoplanetary embryos and low-
mass protoplanets (from a fraction of an Earth mass to a few Earth masses) embedded in a …
