Energetic Particles in the Quiet Corona
Abstract
We address the fates of energetic particles in typical solar minimum coronal magnetic fields. A baseline density of such particles will be set by cosmic ray albedo neutron decay. Other, electromagnetic mechanisms may augment this. PFSS extrapolation is combined with synoptic magnetogram data to constrain the coronal fields, and particle trajectories are determined in the guiding center approximation. We discuss the extent to which solar analogues of terrestrial magnetospheric phenomena (radiation belts, ring current) may exist near solar minimum.
