Description We propose to obtain XMM observations of MASTER OT J1321, a recently identified polar which exhibits strong phase-dependent absorption in optical H and He lines. These emission-absorption reversals coincide with a dramatic, >2 mag rise in the optical light curve, and they provide a rare opportunity to study the structure of the accretion flow as it approaches the accreting white dwarf. The system s magnetic accretion and ^ated mass-transfer rate imply an X-ray bright source. Our proposed observations would enable us to correlate J1321 s unusual optical behavior with the X-ray-emitting accretion region(s) on the white dwarf s surface, and constrain the accretion geometry in a way that is not possible with optical data alone.

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.
