H02: Wave-particle Interactions and Their Effects on Planetary Radiation Belts (2)

Tuesday, August 19  09:40-11:00,  Room #11

Session Chair: Richard Horne

Wave-particle interactions are a ubiquitous physical phenomenon that allows the exchange of energy and momentum between natural plasma waves, and energetic radiation belt particles. In so doing, the wave can act as an energy conduit between different particle energies, species, or both. In this session we discuss the various plasma waves that control planetary radiation belt dynamics, their specific effects on the particles, both individually and in concert, and the various modes of wave-particle interactions, for instance linear, quasi-linear, nonlinear and non-resonant. We welcome both theoretical and observational studies involving the radiation belts of the Earth or other planets. We particularly encourage early results from the Van Allen Probes. Note that studies directed towards radiation belt particle precipitation and its effects are likely better suited to the complementary sessions HG03-HG04.
