Ion-neutral chemistry at icy moons: the case of Ganymede
A. Beth, M. Galand, X. Jia +1
Icy moons orbiting giant planets are often described as airless bodies though they host an exosphere where collisions between neutral species are scarce. In the case of Ganymede, t…

Ionosphere of Ganymede: Galileo observations versus test particle simulation
Arnaud Beth, Marina Galand, Ronan Modolo +3
In this paper, we model the plasma environment of Ganymede by means of a collisionless test particle simulation. By coupling the outputs from a DSMC simulation of Ganymede's exosph…
