Description We propose to observe the high inclination low mass X-ray binary 2S0921-630 in order to test the hypothesis that the residual X-rays seen during eclipse are due to reprocessing and scatttering in an accretion disk corona. By observing atomic emission features from elements such as Ne, Mg, Si, and S at high resolution using RGS1, we can determine the ionization state and emission measure, and thereby infer the density and size of the corona. We can also constrain the elemental abundances. Using the EPIC detectors we can test for variability in the spectrum during the eclipse, and constrain the geometrical extent of the corona. This source is ideal for such a study owing to its demonstrated strong line emission and its long eclipse.

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.
