An Estimation of the Amount of Heating for Some Solar Coronal Loops

Abstract

Based on the standard idea that short cooling times imply continued heating, a method of estimation of the amount of heating is developed and applied to thte five examples of Krieger (1978) assuming conduction to be the dominant cooling mechanism in plane parallel and line dipole geometries. As expected, one requires more heating in former geometry than in the latter. The required total energy supplied by heating is found to be comparable to the total thermal energy of the events under consideration.
