Description | We propose to continue our XMM-Newton observations of new magnetic CVs found in the Sloan Digital Sky Survey. Our results from the first 2 yrs include the identification of the base level of X-ray flux from objects in the lowest states of mass transfer as well as discovery of X-ray eclipses and flares. We propose continuing this work on 7 new systems found in the latest SDSS data, including 3 confirmed Polars and 4 likely Polars-Intermediate Polars. We exploit the high sensitivity and large energy coverage of XMM-Newton to delineate the shock vs blob heating in the typical low accretion regimes encountered in the SDSS data compared to previous X-ray surveys. Our results indicate that low accretion rate systems may represent a large fraction of the magnetic CV population. |

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. |
