Ultraviolet flare activity on the eclipsing binary SZ Piscium.
Abstract
The estimated total chromospheric, transition region and coronal losses for a flare observed on the eclipsing binary SZ Psc with the International Ultraviolet Explorer (IUE) satellite on 6 July 1990 is of the order of 4.5 1036 ergs. This estimate is similar to that derived by Doyle et al. (1989) for an ultraviolet flare on another RS CVn star, II Peg, and is a substantial fraction of the total amount that is possible to store on these stars without having to evoke the presence of kiloGauss fields.
