|Magnetic CVs from SDSS
|Prof Paula Szkody
|We propose to continue our very successful program of XMM-Newton observations of new magnetic CVs found in the SDSS. Results from the past 3yrs include: finding X-rays from the lowest accretion rate magnetic accretors originate only from the companion M star; showing the structure of eclipsed accretion columns; revealing spin pulses in new IPs and flaring in other systems. We propose continuing this work on 7 new systems found in the latest SDSS data, including 2 confirmed Polars and 1 confirmed IP. We exploit the high sensitivity of XMM-Newton to construct good light curves to delineate the geometry of the accretion column or spin of the white dwarf, and the large energy coverage to determine the shock vs blob heating in low accretion rate regimes which are a large fraction of magnetic CVs.

|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.
