| Description | The INTEGRAL and SWIFT satellites detected a large number of galactic X-ray sources above 20keV,among which virgul6-7% identified as accreting white dwarf binaries. Among known systems most harbour asynchronously rotating magnetic primaries, suggesting that this formerly small subclass could be an important contributor to the galactic X-ray binary populations. However, most newly discovered sources are proposed as magnetic cataclysmic variables through optical spectra. XMM-Newton demonstrated unique potential to infer their true nature through the detection of X-ray pulses and study of broad-band spectra. We propose 6 new sources that, if all confirmed as magnetics, will increase by 35% the hard X-ray sample enabling a true census of the first volume-limited sample |

| 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. |
