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…
