The Unknown Hydrogen Exosphere: Space Weather Implications [PDF]
Space Weather, 2018 Recent studies suggest that the hydrogen (H) density in the exosphere and geocorona might differ from previously assumed values by factors as large as 2.

PHEBUS: A double ultraviolet spectrometer to observe Mercury's exosphere [PDF]
Planetary and Space Science, 2010 International audienceProbing of Hermean exosphere by ultraviolet spectroscopy (PHEBUS) is a double spectrometer for the Extreme Ultraviolet range (55-155 nm) and the Far Ultraviolet range (145-315 nm) devoted to the characterization of Mercury's ...

The lunar exosphere: The sputtering contribution
Icarus, 2007Abstract We have extended our Monte Carlo model of exospheres [Wurz, P., Lammer, H., 2003. Icarus 164 (1), 1–13] by treating the ion-induced sputtering process from a known surface in a self-consistent way. The comparison of the calculated exospheric densities with experimental data, which are mostly upper limits, shows that all of our calculated ...

Detection of SO in Io's Exosphere
Science, 2000The Galileo orbiter's close pass by Io in 1995 produced evidence for extensive mass loading of the plasma torus through the ionization of SO 2 . On 11 October 1999, Galileo passed even closer to Io, this time across the upstream side relative to the flow of magnetospheric plasma that corotates with Jupiter.

Exospheres and Atmospheric Escape
Space Science Reviews, 2008Aeronomy is a description of the physics and chemistry of the upper atmospheres and ionospheres of planetary bodies. In this chapter we consider those processes occurring in the upper atmosphere that determine the structure of the corona and lead to molecular escape.

Exospheric model of the plasmasphere
Journal of Atmospheric and Solar-Terrestrial Physics, 2001Abstract ISEE observations indicate that after prolonged quiet periods, the saturated equatorial density decreases exponentially with the radial distance in the plasmasphere. No hydrostatic barometric models fit the saturated equatorial density profiles, since those obtained with barometric maxwellian or lorentzian kinetic models decrease more slowly
