Magnetic activity produces copious UV and X-ray emission in the chromosphere,transition region and corona of late-type stars. Both types of radiation arebelieved to be crucial for the evolution of the atmospheres of the planet buttheir relative importance is not known. While X-rays penetrate deeper into theplanet atmosphere, UV fluxes may be higher and significantly affect the outerlayers of the planet atmosphere. We aim at a comprehensive study of the strengthand range of X-ray and UV fluxes for M dwarfs identified in the GALEX All-SkySurvey. In this proposal we ask for the corresponding X-ray measurements.

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.
