| Abstract | GT-AD Leo is a very active mid-M 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 with the SML window, while one MOS will observe in TIMING mode with the mediumfilter. The OM observes with the UVW2 filter, ideal for flare investigations. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
