Description Period bouncing faint cataclysmic Variables (CVs) with degenerate donor stars
are predicted to represent the majority population among the CV class. Yet only
a handful have been securely identified via IR-photometry and eclipse modeling
and only one was observed at X-ray wavelengths and found to be underluminous by
a large factor. We propose to observe further two of the remaining four objects,
all being eclipsers with well-determined binary parameters and distances, to
measure their accretion rates and thus test the current binary evolution
paradigm.

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.
