We propose to observe 1RXSJ062518.2+733433, a newly discovered intermediatepolar. It is one out of only 5 known IPs showing a distinct soft X-ray componentin addition to the normal hard bremsstrahlung. With the high signal-to-noise XMMX-ray data and simultaneous photometry in the near UV we will determine thespin-period of the white dwarf and the positions of the accretion regions on it.We want to resolve the accretion geometry and get information on the mechanismsof interaction between magnetic field and accreted matter and of energy-release.In this object the soft X-rays are only partially absorbed, so the structure ofthe accretion curtain can be analysed via the time-dependent absorption in both,the hard and soft X-rays -- tracers of material in completely different states.

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.
