On Jovian Plasma Sheet Structure
We evaluate several models of Jovian plasma sheet structure by determining how well they organize several aspects of the observed Voyager 2 magnetic field characteristics as a function of Jovicentric radial distance. The present study focuses exclusively on the data from the Voyager 2 spacecraft because the magnetosphere was more stable during that flyby than it was during the Pioneer 10 and Vo...
متن کاملCharacterization of Jovian Plasma-Embedded Dust Particles
As the data from space missions and laboratories improve, a research domain combining plasmas and charged dust is gaining in prominence. Our solar system provides many natural laboratories such as planetary rings, comet comae and tails, ejecta clouds around moons and asteroids, and Earth’s noctilucent clouds for which to closely study plasma-embedded cosmic dust. One natural laboratory to study...
متن کاملJovian dust streams: Probes of the Io plasma torus
Jupiter was discovered to be a source of high speed dust particles by the Ulysses spacecraft in 1992. These dust particles originate from the volcanic plumes on Io. They collect electrostatic charges from the plasma environment, gain energy from the co-rotating electric field of the magnetosphere, and leave Jupiter with escape speeds over 200 kms. The dust streams were also observed by the Gali...
متن کاملRadio Scintillation Due to Discontinuities in the Interstellar Plasma Density
We develop the theory of interstellar scintillation as caused by an irregular plasma having a power-law spatial density spectrum with a spectral exponent of β = 4 corresponding to a medium with abrupt changes in its density. An “outer scale” is included in the model representing the typical scale over which the density of the medium remains uniform. Such a spectrum could be used to model plasma...
متن کاملDouble discontinuities at the magnetotail plasma sheet-lobe boundary
A double discontinuity is a compound structure composed of a slow shock layer and an adjoining rotational discontinuity layer on the postshock side. We use highresolution data from Geotail and Wind spacecraft to examine the interior structure within the finite thickness of the discontinuity at the plasma sheet-lobe boundary and found that recognizable MHD structures at the boundary can be stand...
