Abstract We propose to obtain X-ray fluxes and spectra of 8 new magnetic CVs identifiedduring the first 2 yrs of the Sloan Digital Sky Survey. The Polars in this grouprepresent the lowest end of mass transfer in magnetic systems. We will exploitthe high sensitivity and large energy coverage of XMM to delineate the shock vsblob heating in these low accretion regimes as compared to the high accretionrate systems that have previously been found in X-ray surveys. Our findings fromSDSS indicate these low accretion systems may represent a large contribution tothe magnetic CV population. Thus, determining their accretion characteristicsprovides an important test of accretion scenarios at high magnetic fields.

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.
