Abstract Swift J1749.4-2807 is the first (and only) eclipsing accreting X-ray millisecondpulsar. At variance with all the other transient low mass X-ray binaries, SwiftJ1749 is the only source showing eclipses and a hard component in its X-rayquiescent spectrum. This opens the unique opportunity to discriminate betweenmodels that have been proposed for the quiescent emission of neutron startransients. Based on a detailed feasibility we need to follow Swift J1749 forthree orbital periods, totalling 100 ks, to probe the quiescent spectrum with aneclipse mapping technique.

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.
