Description GT-EV Lac is a very active mid-M type flare star that produces up to one optical flare per hour. The role of flare heating of the corona can ideally be studied with this source. The EPIC cameras can be used to identify numerous weak 'statistical. flares, while the RGS will be used to monitor parameters such as density, abundances, and temperatures during larger flares. Results will be compared with the quiescent state. Simultaneous radio VLA observations will be requested to study energy release physics. The pn camera operates in with the SML window, while one MOS will observe in TIMING mode with the medium filter. The OM observes with the UVW1 filter, ideal for flare investigations.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
