| Abstract | GT- We want to use the XMM EPIC camera to observe a carefully selected sampleof cool stars located on key positions in the H-R diagram, MS and pre-MS stars.The goal of our observations is to obtain good S/N spectra and metal abundancesof one example of each of the different classes of stars. Our observations onAlgol and YY Gem are time-critical for simultaneous observations with Chandra.On Algol and CF Tuc, we request continuous observations centered on a primaryeclipse. On YY Gem, our observation should be continuous, too, to cover thefull orbit. HR 1084 is a calibration target for stray light monitoring with thetransparent filter, but we need to do our GT observation with the thin 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. |
