Abstract | An unexpected large fraction of Cataclysmic Variables (CVs) has been identifiedas optical counterparts of hard X-ray sources in the INTEGRAL and Swift surveys.Most of them belong to the magnetic class of the Intermediate Polars (IPs),suggesting a potentially important role in the study of galactic populations ofX-ray sources. To date many new CVs still need to be properly classified. Herewe propose to observe 6 new hard X-ray CV systems to detect X-ray pulsations atthe white dwarf rotational period which, together with their spectralproperties, will provide firm constraints on their suspected magnetic nature. |

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. |
