|Title||New SDSS Magnetic CVs with Unusual Accretion Rates|
|Author||Prof Paula Szkody|
|Description||We will obtain fluxes and spectra for 5 new magnetic cataclysmic variables (Polars) identified from the first year of the Sloan Digital Sky Survey. These objects are unusual in that they appear to represent the low end of mass transfer in magnetics and have low X-ray-optical fluxes compared to X-ray selected Polars. We will use the high sensitivity and large energy coverage of XMM to delineate the shock versus blob heating in this low accretion situation as compared to the high accretion states that are usual in X-ray selected magnetics. These results will test the available accretion models in high magnetic field regimes.|

|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.
