Macroscopic electric fields during two-ribbon flares.
Abstract
Large-scale electric fields present during solar flares might provide a mechanism for continuously accelerating particles to high energies. The authors use the magnetic reconnection model of two-ribbon flares (Kopp et al., 1976, 1984) to calculate the temporal variation of the coronal electric field for the large flares of 29 July, 1973 and 21 May, 1980. This calculation shows that the electric field declines monotonically during the decay phase. The authors conclude that the actual reconnection rate after these two-ribbon flares is being governed by the global dynamics of the perturbed coronal field-plasma system, rather than by processes within the magnetic diffusion region itself.
