| Description | In XMM/AO18, we embarked on a project to reveal previously unrecognized magnetic CVs, based on common (though not universal) optical fingerprints. This has led to the successful discovery of a low luminosity intermediate polar (LLIP), which we are continuing in our AO20 program. In this proposal, we request fullfill observation of a sample of supposed dwarf novae with high Fx/Fopt ratios and high X-ray luminosity, making them excellent candidates to be previously unrecognized LLIPs. If many of our targets are confirmed as LLIPs, their space density 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 the evolution of magnetic white dwarfs in interacting binaries. |

| 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. |
