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 کاملElectron Signatures of Satellite Sweeping in the Magnetosphere of Uranus
The Voyager 2 Cosmic Ray System found large-scale macrosignatures of satellite sweeping for MeV electrons near the orbits of the satellites Miranda, Ariel, and Umbriel in the magnetosphere of Uranus. Due to the large magnetic inclinations of satellite orbits at Uranus, sweeping rates vary along the orbits with the McIlwain L parameter. However, no evidence was found, where expected, for fresh s...
متن کاملDisk-satellite Interactions
We calculate the rate at which angular momentum and energy are transferred between a disk and a satellite which orbit the same central mass. A satellite which moves on a circular orbit exerts a torque on the disk only in the immediate vicinity of its Lindblad resonances. The direction of angular momentum transport is outward, from disk material inside the satellite's orbit to the satellite and ...
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 کاملMean-motion resonances in satellite–disc interactions
Mean-motion resonances between a Keplerian disc and an orbiting companion are analysed within a Hamiltonian formulation using complex canonical Poincaré variables, which are ideally suited to the description of eccentricity and inclination dynamics. Irreversibility is introduced by allowing for dissipation within the disc. A method is given for determining the rates of change of eccentricity an...
