Description We propose to observe with XMM three Millisecond X-ray Pulsar Transients for 20 ks each in order to measure the source luminosity during quiescence. Since for these sources the spin period is known, this will allow us to put a firm upper limit on the neutron star magnetic field strength. This study will provide valuable information about the link between low mass X-ray binaries and binary millisecond radio pulsars. Moreover, the study of the cooling of the neutron star during quiescence is a powerful tool to investigate its physical structure and to determine r^ant parameters like its mass and its equation of state. The XMM observation will also provide a precise position of these sources allowing the identification and-or study of their optical, infrared and radio counterparts.

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.
