Atmospheric loss from planetary atmospheres is an important geophysical problem with
implications for planetary evolution. This is a multidisciplinary research field that requires an …

The habitability of the surface of any planet is determined by a complex evolution of its
interior, surface, and atmosphere. The electromagnetic and particle radiation of stars drive …

Observations of planetary auroras form a new area of planetary exploration from space,
especially for nonmagnetic planets since various kinds of auroras like Discrete, Proton and …

A 1-D collisional Monte Carlo model of Europa's atmosphere is described in which the
sublimation and sputtering sources of H2O molecules and their molecular fragments are …

We have studied the mutual neutralization reaction of vibronically cold NO+ with O-at a
collision energy of≈ 0.1 eV and under single-collision conditions. The reaction is completely …

A model of the photoelectron collision‐induced component of the Mars dayglow using recent
cross sections and solar flux is described. The calculation of the photoelectron source of …

We present an analysis of hundreds of middle ultraviolet auroral spectra collected at the limb
with the Imaging UltraViolet Spectrograph (IUVS) instrument on board the Mars Atmosphere …

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 …

Martian aurorae have been detected with the SPICAM instrument on board Mars Express
both in the nadir and the limb viewing modes. In this study, we focus on three limb …

The STIS and ACS instruments onboard HST are widely used to study the giant planet's
aurora. Several assumptions have to be made to convert the instrumental counts into …
