| Description | Magnetic cataclysmic variables are binary systems which contain a highly magnetic white dwarf accreting matter along its magnetic field lines from a late-type companion. It has recently been found that a particular class of these systems known as intermediate polars occasionally enter previously unanticipated ..low states,. during which the accretion-rate, and therefore flux, mysteriously decreases. Deep, pointed X-ray observations of these low states are rare, so we propose a 50ks XMM-Newton Target of Opportunity observation of the next intermediate polar to enter such a state, in order to investigate the accretion mechanisms (or lack thereof) in this poorly understood low-flux regime. |

| 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. |
