Description | GT- We want to use the XMM EPIC camera to observe a carefully selected sample of 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 abundances of one example of each of the different classes of stars. Our observations on Algol and YY Gem are time-critical for simultaneous observations with Chandra. On Algol and CF Tuc, we request continuous observations centered on a primary eclipse. On YY Gem, our observation should be continuous, too, to cover the full orbit. HR 1084 is a calibration target for stray light monitoring with the transparent filter, but we need to do our GT observation with the thin filter. |

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. |
