About ten per cent of the known extrasolar planets are gas giants that orbit very close to their parent stars. The atmospheres of these 'hot Jupiters' are heated by the immense stellar irradiation. In the case of the planet HD 209458b, this energy de

Spectral images of the Io plasma torus obtained from ∼165 hours of observation by the Extreme Ultraviolet Explorer (EUVE) spacecraft during the 124 encounter of the Galileo spacecraft with the torus and at an earlier epoch in 1996 are analyzed by a

We analyzed about 47 hours of Voyager 1 ultraviolet spectrometer observations of the Io plasma torus in order to determine the distributions of ion and electron density and electron temperature as five-dimensional functions of (1) radius (L), (2) Sys

Far and extreme ultraviolet observations of Uranus and Neptune, principally by the ultraviolet spectrometer (UVS) on Voyager 2, are reviewed. Occultation observations have characterized the temperature, energy deposition, and major-constituent compos

One of the torus characteristics of most interest for understanding torus energization is its electron temperature T e . Yet deriving T e has always been difficult because the measured quantity (emission brightness) is controlled jointly by T e and o

A model for the generation of the Io plasma torus “ribbon” density feature is proposed. In this model a self-regulation mechanism for plasma pressure is hypothesized, operating through ring current inhibition of flux-tube interchange transport. T

We have analyzed Voyager 2 ultraviolet spectrometer observations of the H Lyman α emission from the atomic hydrogen corona of Uranus. The resulting estimated hydrogen density distribution has a radial profile ∝ 1/r2. This distribution implies a we

Extreme Ultraviolet Explorer satellite observations of Jupiter's Io plasma torus conducted over a two-year time period before, during and after the impacts of comet Shoemaker-Levy/9 reveal that no new spectral features appeared in the 400–715 A spe

By the time of the impact of comet P/Shoemaker-Levy 9 with Jupiter, the freshly-broken surfaces of the accompanying rubble will have been outgassing for about two years, and will have produced an expanding and co-moving cloud of gas hundreds of R(sub
