Ion cyclotron waves: a tool for characterizing neutral particle profiles in extended exospheres

Frontiers in Astronomy and Space Sciences
Planetary exospheres are usually observed using transit spectroscopic methods, such as the Lyman-α line, which is mainly limited by interstellar medium absorption and airglow contamination from the geocorona when using low-orbit space telescopes or ...

Monte Carlo Calculation of Electron Energy Degradation in a Pure O2 Atmosphere

The Astrophysical Journal
Electron degradation serves as a significant energy source in planetary upper atmospheres. In this study, a Monte Carlo model is constructed to investigate the degradation of electrons in a pure O _2 atmosphere under the local approximation. Both elastic
