Abstract:
In this paper a theory of cooling of solar coronal loops through conduction driven evaporation in presence of a source of heating is presented. No attempt has been made to specify the nature of the source. The theory has been applied to estimate the amount of heating for the flare kernael of 1973 September 1 for different breadths of the source of heating. These results are then compared with those of Elwert & Narian (1980).
