Description We propose to continue monitoring the dipping low-mass X-ray binary EXO 0748-676 as it moves into quiescence. RXTE first reported its detection at the lowest flux level since the beginning of the RXTE mission in 1996 in pointed observations during August 2008 (ATel #1736). Swift observations in October 2008 confirmed the likely cessation of accretion activity (ATel #1812). The cooling of the neutron star crust has been subsequently monitored with XMM observations every 4 months (this proposal, Part I). The last of these observations shows that the cooling of the crust is still continuing. A further observation of EXO 0748-676 is important to determine the cooling curve of the neutron star crust, which has been heated during by more than 20~years of accretion.

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.
