Protoplanet Magnetosphere Interactions
Aims. 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. Methods. We have calculated the gravitational interaction of the protoplanet with the magnetosphere using a local model and determined the rate of evolution of the orbit. Results. The in...
متن کاملThe chronostratigraphy of protoplanet Vesta
In this paper we present a time-stratigraphic scheme and geologic time scale for the protoplanet Vesta, based on global geologic mapping and other analyses of NASA Dawn spacecraft data, complemented by insights gained from laboratory studies of howardite–eucrite–diogenite (HED) meteorites and geophysical modeling. On the basis of prominent impact structures and their associated deposits, we pro...
متن کاملDynamics of Spacecraft Plume/Magnetosphere Interactions in Geostationary Earth Orbit
Detailed direct simulation Monte Carlo/Particle in Cell simulations involving the interaction of a hydrazine chemical rocket plume with the rarefied ambient magnetosphere are presented for steady thruster firings in geostationary Earth orbit (GEO). The hydrazine chemical rocket plume is modeled as a neutral gas mixture with thruster exit conditions corresponding to a mass flow rate of 5.0 × 10−...
متن کاملDisk surface density transitions as protoplanet traps
The tidal torque exerted by a protoplanetary disk with power law surface density and temperature profiles onto an embedded protoplanetary embryo is generally a negative quantity that leads to the embryo inwards migration. Here we investigate how the tidal torque balance is affected at a disk surface density radial jump. The jump has two consequences : • it affects the differential Lindblad torq...
متن کاملOn disc protoplanet interactions in a non-barotropic disc with thermal diffusion
Aims. We study the disc planet interactions of low-mass protoplanets embedded in a circumstellar disc. We extend the standard theory of planet migration from the usual locally isothermal assumption to include non-barotropic effects, focusing on the validity of linear theory. Methods. We compared solutions of the linear equations with results from non-linear hydrodynamic simulations, where in bo...
