Particle Acceleration and Transport at the Sun and in the Inner Heliosphere

Session ID#: 71420

Session Description:
An important topic of solar and heliospheric physics is to understand the acceleration and transport of nonthermal particles.  Such studies in the inner heliosphere encompass a variety of processes leading to the formation of solar wind suprathermal particles, solar energetic particles, energetic particles from Corotating Interaction Regions, etc. However, many details of the acceleration and transport process of these energetic particles still remain unknown. Particle acceleration processes include magnetic reconnection, wave-particle interactions, collisionless shock waves, etc., and particle transport processes include adiabatic cooling, parallel and perpendicular diffusion, random walk of magnetic field lines, etc.

This session invites contributions that discuss space-borne and ground-based observations, and theory/modeling of the processes pertaining to particle acceleration and transport at the Sun and in the inner heliosphere.
