Description We propose to observe EY Cyg, a dwarf nova that shows signatures of a past nova explosion, an ideal target to study the physics of accretion. It is a known X-ray source at low inclination, and a long period system, allowing a useful comparison with two short period novae recently observed in X-rays at quiescence, and with dwarf novae atlow inclination. EY Cyg is also one of very few relatively X-ray bright cataclysmic variables at quiescence, but it has never been observed in X-rays except for very short, mostly serendipitous exposures. We have already studied this system in great detail at ultraviolet and optical wavelengths, but good quality data in the X-ray range are still missing.

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.
