A simulation approach of high-frequency electrostatic waves found in Saturn's magnetosphere

Koen, Etienne J.; Collier, Andrew B.; Maharaj, Shimul K.

Using a particle-in-cell simulation, the characteristics of electron plasma and electron acoustic waves are investigated in plasmas containing an ion and two electron components. The electron velocities are modeled by a combination of two κ distributions. The model applies to the extended plasma sheet region in Saturn's magnetosphere where the coo…

Potential structure around the Cassini spacecraft near the orbit of Enceladus

Miloch, W. J.; Olson, J.; Ratynskaia, S. +1 more

We present the results of numerical simulations of the potential structure around an object in a streaming plasma with parameters relevant for the Cassini spacecraft passing through Saturn's plasma disk near the orbit of Enceladus. Two- and three-dimensional particle-in-cell codes have been used allowing the potential of the simulated spacecraft b…
