The Differential Emission Measure of Dynamic Coronal Loops,

Abstract

Although most of the observations of soft x-ray and UV emission from stellar sources can be adequately explained in terms of static models of coronal loops, there are now several observations in soft x-rays of a solar-like flare from a stellar flare source (e.g. Johnson 1981, Kahler 1981; Stern, et al. We discuss the effects of time dependent phenomena, such as flare energization and decay, on the temperature and density structure of the transition region and, in particular, on the form of the differential emission measure. We find that unlike the case of the static models, the form of the differential emission measure can be used to determine the important physical mechanisms in the dynamic models.
