Propagation of Transient Perturbations into a Planet's Exosphere: Molecular Kinetic Simulations
Ludivine Leclercq, Robert E. Johnson, Hayley H Williamson +1
The upper atmospheres of Mars and Titan, as well as those on many other planetary bodies, exhibit significant density variations vs. altitude that are interpreted as gravity waves.…

On the orbital variability of Ganymede's atmosphere
Francois Leblanc, Apurva V. Oza, Ludivine Leclercq +5
Ganymede's atmosphere is produced by radiative interactions with its surface, sourced by the Sun and the Jovian plasma. The sputtered and thermally desorbed molecules are tracked i…

Dusk Over Dawn O Asymmetry in Europa's Near-Surface Atmosphere
Apurva V. Oza, Francois Leblanc, Robert E. Johnson +4
The evolution of Europa's water-product exosphere over its 85-hour day, based on current models, has not been shown to exhibit any diurnal asymmetries. Here we simulate Europa's ex…
