A one-dimensional (1-D) model coupling a two-stream electron transport model of energy deposition with a 1-D thermal conduction model has been developed. It is applied to investigate the links…
Morphological differences between Saturn's ultraviolet aurorae and those of Earth and Jupiter
It has often been stated that Saturn's magnetosphere and aurorae are intermediate between those of Earth, where the dominant processes are solar wind driven, and those of Jupiter, where processes are…

[1] This paper reports a study of Jupiter's polar auroral emissions observed in an extended series of FUV images. They were obtained on seven days, during winter 2000–2001, with the STIS camera on…
Open flux estimates in Saturn's magnetosphere during the January 2004 Cassini‐HST campaign, and implications for reconnection rates
During 8–30 January 2004, a sequence of 68 UV images of Saturn's southern aurora was obtained by the Hubble Space Telescope (HST), coordinated for the first time with measurements of the upstream…
Ultraviolet emissions from the magnetic footprints of Io, Ganymede and Europa on Jupiter
It is shown that Io's magnetic footprint extends well beyond the immediate vicinity of Io's flux-tube interaction with Jupiter, and much farther than predicted theoretically; the emission persists for several hours downstream.
Characteristics of Saturn's FUV aurora observed with the Space Telescope Imaging Spectrograph

[1] We analyze a set of 15 FUV images obtained between October 1997 and January 2001 with the Hubble Space Telescope Imaging Spectrograph (STIS), providing a good view of Saturn's south auroral oval.…
Far ultraviolet imaging from the IMAGE spacecraft. 3. Spectral imaging of Lyman-α and OI 135.6 nm

- 2000
Two FUV Spectral imaging instruments, the Spectrographic Imager (SI) and the Geocorona Photometer (GEO) provide IMAGE with simultaneous global maps of the hydrogen (121.8 nm) and oxygen 135.6 nm…
Auroral evidence of Io's control over the magnetosphere of Jupiter

- 1 January 2012
Contrary to the case of the Earth, the main auroral oval on Jupiter is related to the breakdown of plasma corotation in the middle magnetosphere. Even if the root causes for the main auroral…
