The effect of particle precipitation events on the neutral and ion chemistry of the middle atmosphere: II. Odd hydrogen
- D. Rusch, J. Gérard, S. Solomon, P. Crutzen, G. Reid
- Chemistry
- 1 July 1981
A one dimensional time-dependent model of the neutral and ion chemistry of the middle atmosphere has been used to examine the production of odd hydrogen (H, OH, and HO2) during charged particle… Expand
A self‐consistent model of the Jovian auroral thermal structure
- D. Grodent, J. Waite, J. Gérard
- Materials Science
- 1 July 2001
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… Expand
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… Expand
Ultraviolet emissions from the magnetic footprints of Io, Ganymede and Europa on Jupiter
TLDR
Jupiter's polar auroral emissions
- D. Grodent, J. Clarke, J. Waite, S. Cowley, J. Gérard, Jihyun Kim
- Physics
- 1 October 2003
[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… Expand
Variable morphology of Saturn's southern ultraviolet aurora
- D. Grodent, J. Gérard, S. Cowley, E. Bunce, J. Clarke
- Physics
- 1 July 2005
[1] The Space Telescope Imaging Spectrograph camera on board Hubble Space Telescope obtained 68 FUV images of Saturn's southern auroral emission between 8 and 30 January 2004, during Cassini's… Expand
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… Expand
Characteristics of Saturn's FUV aurora observed with the Space Telescope Imaging Spectrograph
- J. Gérard, D. Grodent, J. Gustin, A. Saglam, J. Clarke, J. Trauger
- Physics
- 1 September 2004
[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.… Expand
Recurrent energization of plasma in the midnight-to-dawn quadrant of Saturn's magnetosphere, and its relationship to auroral UV and radio emissions
- D. Mitchell, S. Krimigis, +11 authors W. Pryor
- Physics
- 1 December 2009
Abstract We demonstrate that under some magnetospheric conditions protons and oxygen ions are accelerated once per Saturn magnetosphere rotation, at a preferred local time between midnight and dawn.… Expand
Altitude of Saturn's aurora and its implications for the characteristic energy of precipitated electrons
- J. Gérard, B. Bonfond, +4 authors V. Shematovich
- Physics, Geology
- 2009
[1] Images of Saturn's aurora at the limb have been collected with the Advanced Camera for Surveys on board the Hubble Space Telescope. They show that the peak of Saturn's nightside emission is… Expand
