GT Observations of Active Cool Stars: EV Lac

GTEV Lac is a very active midM type flare star that produces up to one opticalflare per hour. The role of flare heating of the corona can ideally be studiedwith this source. The EPIC cameras can be used to identify numerous weak statistical. flares, while the RGS will be used to monitor parameters such asdensity, abundances, and temperatures during larger flares. Resultswill be compared with the quiescent state. Simultaneous radio VLA observationswill be requested to study energy release physics. The pn camera operates inwith the SML window, while one MOS will observe in TIMING mode with the mediumfilter. The OM observes with the UVW1 filter, ideal for flare investigations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
