Plasma Motions in Planetary Magnetospheres

Science, 1991
Before direct exploration by spacecraft, Jupiter was the only planet other than Earth that was known to have a magnetic field, as revealed by its nonthermal radio emissions. The term "magnetosphere" did not exist because there was no clear concept of such an entity.

Planetary Ionospheres and Magnetospheres

2008
We begin this chapter with a detailed review of the ionization and recombination processes in a planetary ionosphere, as exemplified by the ionosphere we know the most about, that of the Earth. We then extend the discussion to the ionospheres of Mars and Venus, and examine atmospheric loss mechanisms.

Dust in planetary magnetospheres

Advances in Space Research, 1993
Abstract Dust particles immersed in the magnetized plasma environment of planetary magnetospheres collect electrostatic charges. The expected charges are modest and only micron and smaller grains will be significantly perturbed by the resulting electrodynamic forces. These electrodynamic perturbations compete with other processes - radiation pressure,

The dynamics of planetary magnetospheres

Planetary and Space Science, 2001
Abstract Mercury, Earth, Jupiter, Saturn, Uranus, Neptune, and the moon, Ganymede, have presently-active internal dynamos while Venus, Mars, at least two of the Galilean moons, the Earth's moon, comets and asteroids do not. These active dynamos produce magnetic fields that have sufficient strength to stand off the pressure of the exterior plasma ...

Reconnection in planetary magnetospheres

Advances in Space Research, 2000
Current sheets in planetary magnetospheres that lie between regions of "oppositely-directed" magnetic field are either magnetopause-like, separating plasmas with different properties, or tail-like, separating plasmas of rather similar properties. The magnetopause current sheets generally have a nearly limitless supply of magnetized plasma that can ...

Modeling planetary magnetospheres

Reviews of Geophysics, 1983
There has been a marked change in the character of magnetospheric modeling during the past quadrennium. In earlier studies, the emphasis was on describing the average magnetospheric properties. These descriptive models were empirical or semiempirical and provided a static picture of the magnetospheric configuration.

Particle acceleration in planetary magnetospheres

Nature, 1974
MEASUREMENTS of energetic particle fluxes in space1,2 have stimulated interest in the problem of particle acceleration inside planetary magnetospheres. Suggestions that terrestrial auroral (keV) electron precipitation is associated with transient space charge effects3, have been discarded, largely because the parallel (plasma) electrical conductivity ...

ULF waves in planetary magnetospheres

2006
Ultra-low frequency (ULF) waves are messengers in space plasmas. They communicate information about unstable, free-energy-containing plasma configurations, transient phenomena, or obstacles in flowing plasmas; they transport energy between different parts of magnetospheric systems; and they serve as momentum coupling agents between remote regions such ...
