We propose to monitor the dipping low-mass X-ray binary EXO 0748-676 as it turnsoff and becomes quiescent. RXTE pointed observations of EXO 0748-676 duringAugust 2008 show the source at the lowest flux level since the beginning of theRXTE mission in 1996, indicating that X-ray activity may cease soon, after beinga steady accreting X-ray binary since February 1985 (ATel #1736). The proposedXMM observations aim to look at the source both as it turns off and in theperiod after it ceases X-ray activity to determine the cooling of the neutronstar crust, which has been heated by more than 20 years of outburst.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
