Description GT- EX Hya is an eclipsing intermediate polar-type CV with an orbital period of 98 min and a white dwarf spin period of 67 min. The source.s spectacular ASCA spectrum has been analyzed and interpreted by Fujimoto & Ishida (1997) and Allan, Hellier, and Beardmore (1997) with differing conclusions about the elemental abundances and the applicability of the Aizu model of the accretion column. We propose to utilize the large area, wide bandpass, and high spectral resolution of XMM to resolve these discrepancies. With the RGS spectrum we will for example strongly constrain the density of the plasma from the line ratios of Fe L-shell transitions and the low-temperature end of the DEM distribution from the K alpha emission line ratios of H- and He-like O, Ne, Mg, and Si.

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.
