We propose to constrain the X-ray properties of two relatively poorly studiedsubclasses of magnetic catalysmic variables (mCVs): asynchronous polars (APs)and near-synchronous intermediate polars (nsIPs), sometimes regarded as themissing link in the evolution of mCVs. This is timely for such studies: werecently discovered a dozen of periodic X-ray sources in the Galactic CenterRegion (CGR) that appear to have periods and X-ray properties similar to someAPs and nsIPs. A general X-ray picture of both is needed to determine theirconnection to thousands of the GCR X-ray sources that are generally consideredto be mainly mCVs.

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.
