SM009:
Energetic Particles as Tracers of Magnetospheric Processes





Session ID#: 22946

Session Description:
Energetic particles (E > 10’s keV) provide important information concerning fundamental physical processes central to solar wind-magnetosphere interactions that take place within the foreshock, at the bow shock, in the magnetosheath, and at the magnetopause of planets with and without magnetospheres. Both Fermi and shock drift acceleration have been proposed to occur at the bow shock and upstream within the foreshock, whereas magnetic reconnection can energize particles at the magnetopause and allow magnetospheric particles to escape. The energetic electrons measured from high-latitude LEO can be used to determine the nature of loss processes occurring at lower latitudes magnetosphere. Energetic particles can also be used as tracers to remotely sense magnetic field boundaries or to determine whether spacecraft are on open or closed magnetic field lines. This session focusses on studies including energetic particles as remote sensors of various space plasma phenomena. We solicit abstracts from both observational and theoretical/modeling studies.
