Protoplanet Magnetosphere Interactions [PDF]
Astronomy & Astrophysics, 2006 In this paper, we study a simple model of an orbiting protoplanet in a central magnetospheric cavity, the entry into such a cavity having been proposed as a mechanism for halting inward orbital migration.

The Migration and Growth of Protoplanets in Protostellar Discs [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We investigate the gravitational interaction of a Jovian mass protoplanet with a gaseous disc with aspect ratio and kinematic viscosity expected for the protoplanetary disc from which it formed.

Protoplanet Dynamics in a Shear-Dominated Disk [PDF]
The Astronomical Journal, 2006 The velocity dispersion, or eccentricity distribution, of protoplanets interacting with planetesimals is set by a balance between dynamical friction and viscous stirring.

Oligarchic Growth of Protoplanets in Planetesimal Rings
The Astrophysical JournalIn the standard planet formation scenario, planetesimals are assumed to form throughout the protoplanetary disk and to be smoothly distributed in the radial direction except for the snowline.

Core Formation in Giant Gaseous Protoplanets [PDF]
Icarus, 2008 Sedimentation rates of silicate grains in gas giant protoplanets formed by disk instability are calculated for protoplanetary masses between 1 M_Saturn to 10 M_Jupiter.

An approximation for the capture radius of gaseous protoplanets [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2021 ABSTRACT Determining the heavy-element accretion rate of growing giant planets is crucial for understanding their formation and bulk composition. The solid (heavy-element) accretion rate should be carefully modelled during the various stages of giant planet formation and therefore the planetary capture radius must be determined.

Outflows Driven by Giant Protoplanets [PDF]
The Astrophysical Journal, 2006 We investigate outflows driven by a giant protoplanet using three-dimensional MHD nested grid simulations. We consider a local region around the protoplanet in the protoplanetary disk, and calculate three models: (a) unmagnetized disk model, (b) magnetized disk model having magnetic field azimuthally parallel to the disk, and (c) magnetic field ...
