Description Low-accretion rate polars escaped detection in the RASS and were discovered recently in chance in optical surveys (HQS, SDSS) as CVs in permanent states of low accretion. The presence of such systems is not predicted by current theories of CV evolution. Establishing their detailed properties is the first important step in understanding their role in this respect. We propose XMM-Newton observations with full-phase coverage of the brightest of the presently known 4 systems. With EPIC we test the bombardement accretion scenario. With the OM we determine the photospheric temperature distribution of the accreting white dwarf. This experiment is important for our understanding of the secular heating and cooling processes in accreting magnetic white dwarfs.

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.
