X-Ray Emission from Flare Collapsing Trap
Abstract
An acceleration process in the collapsing magnetic trap, formed in the flare with cusp magnetic field topology, is described. Computations show that high-energy electrons are accumulated in the central part of the collapsing magnetic trap due to an increase of their pitch angles. The effect explains in a natural way the formation of X-ray loop-top sources. Then, using the model with the collapsing trap and considering only the adiabatic heating process, a possible explanation for the motion of the X-ray loop-top source observed at the beginning of some cusp-type flares is presented.
