| Abstract | We propose XMM-Newton observations of 4 newly discovered long-period AM CVnsystems. Our goals are\: (1) determine the X-ray fluxes of these objects to helpunderstand how they can be identified in future surveys and test the nature ofthe X-ray emission region (2) do eclipse mapping in both X-ray and UV tounderstand the relative contributions of the accreting white dwarf and boundarylayer versus the larger accretion disks (3) if the systems are on the bright endof the possible range (which is likely), use their X-ray spectral shapes toestimate their masses from cooling flow models, while if they are on the faintend, use the measured fluxes to plan future longer observations. |

| 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. |
