Phenomena related to electron beams in solar flares
Abstract
Starting from basic observational characteristics of solar flares the flare physical processes are briefly described. The role of electron beams in such a flare scenario is expressed. The observational manifestations of electron beams as, e.g., type III and U radio bursts are presented. Then results of numerical modelling of these processes are shown. Besides the magnetic field-line reconnection process which is considered to be a primary flare one, the main attention is devoted to the evolution of electron beams in flare loops, to the interpretation of U bursts, to the electron beam bombardment of deep and dense layers of the solar atmosphere and to accompanied processes as the evaporation process and the asymmetry of optical chromospheric lines.
