Abstract
In view of the importance of these objects as observational probes for theories of stellar dynamos and coronal heating, as well as their potentially important role in the galactic environment, we implemented a program of pointed ROSAT PSPC observations of selected M dwarfs in the solar neighborhood. We derive key coronal plasma parameters based on the observed PSPC pulse-height distributions in order to investigate stellar coronal structure in more detail. In particular, we utilize temperatures and emission measures inferred for one or more distinct coronal components as constraints for the development of semi-empirical magnetic loop models as representations of the coronae of low mass stars (Giampapaet al. 1995).
