Description Swift J1749.4-2807 is the first (and only) eclipsing accreting X-ray millisecond pulsar. At variance with all the other transient low mass X-ray binaries, Swift J1749 is the only source showing eclipses and a hard component in its X-ray quiescent spectrum. This opens the unique opportunity to discriminate between models that have been proposed for the quiescent emission of neutron star transients. Based on a detailed feasibility we need to follow Swift J1749 for three orbital periods, totalling 100 ks, to probe the quiescent spectrum with an eclipse mapping technique.

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.
