| Abstract | GT-UV Cet is a binary of two low-mass dMe stars at a distance of 2.6 pc. Theircombined light curve is continuously variable due to the presence of numerousflares. This star is ideal to study the role of relatively modest flares forcoronal heating. By combining observations with radio VLA and possibly VLBAobservations, we will investigate details of the flare energy release, flarestatistics, and flare heating. The RGS will be used to search for mass motions,density and abundance variations during flares, and to obtain, together with theEPICs, detailed time-dependent emission measure distribution models. One MOS isin TIMING mode, and the pn camera will be used in SML window/medium filter modeto optimize for soft photons. The OM will operate with the UVW1 filter. |

| 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. |
