On the temperature distribuiton along a solar flare loop

Abstract

We have obtained expressions for temperature distribution along a solar flare in the presence of a source of continued heating in constant cross section and line dipole geometries under nonstatic conditions. The quantitative results are presented for the flare kernel of 1973 September 1 for sources of small and large extensions. It is found that the fall of temperature in constant cross section geometry is faster than that in line dipole geometry. The rate of fall is faster under static conditions than under nonstatic ones. Further, the fall of temperature is faster if the source is stronger and confined to a smaller region at the top of the loop than when the whole loop is heated by a weaker source.
