Particle Simulations of Magnetospheric Plasmas

Abstract

Plasma physics processes occurring in magnetospheric plasmas are studied by means of numerical simulations. This study has included the excitation of instabilities due to electron currents and/or ion beams due to the presence of nonuniform electric fields. Our investigations also included the heating and transport of plasma in the presence of particle interactions with excited waves in a collisionless plasma. Extensive numerical simulations have been performed along with the development of analytic theories. These simulations allowed us to assess the affect of inherent nonlinear processes on plasma dynamics and to compare the simulation results with the observed data. Keywords: Particle simulations; Magnetospheric plasmas.
