Scientific paper

We propose HETGS observations of ER Vul lasting two orbital periods (P = 60 ksec) to obtain time-resolved coronal emission line spectra. ER Vul is the brightest short-period RS CVn binary in X-rays. Despite showing a partial optical eclipse, no X-ray eclipses are evident. Instead continuous small-scale flaring is seen. We shall investigate the temporal variability of the coronal temperature and EM distributions, estimate density and abundance variations, and model the changing coronal plasma conditions. Contemporaneous radio and optical monitoring will be used to study the nonthermal electron population and starspot distribution. Study of extreme activity on Sun-like stars extends our ability to understand the causes of solar activity with its direct effects on the Earth.
