| Abstract | In XMM/AO18, we embarked on a project to reveal previously unrecognized magneticCVs, based on common (though not universal) optical fingerprints. This has ledto the successful discovery of a low luminosity intermediate polar (LLIP), whichwe are continuing in our AO20 program. In this proposal, we request fullfillobservation of a sample of supposed dwarf novae with high Fx/Fopt ratios andhigh X-ray luminosity, making them excellent candidates to be previouslyunrecognized LLIPs. If many of our targets are confirmed as LLIPs, their spacedensity may be comparable to, or higher than, typical intermediate polars (IPs)that are more X-ray luminous. LLIPs may well be the missing links in theevolution of magnetic white dwarfs in interacting binaries. |

| 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. |
