Energy Release and Particle Acceleration in Complex Active Regions
Abstract
Photospheric fluid flows and magnetic fields, magnetic energy release and particle acceleration have been treated so far as separate issues. In the widely used model the impulsive energy release (flares) is related to the 3D reconnection in current sheet(s), which are adjusted to simple magnetic topologies (magnetic loops). MHD turbulence generated from the reconnecting sheet fill the adjusted loop(s) and accelerate particles. We will review the strong and weak points of this scenario and attempt to generalized it, for complex and possibly more realistic magnetic topologies generated by the extrapolation of observed photospheric magnetic fields.
