|Title||Accreting millisecond NS transients in quiescence: the case of IGR J0029+5934|
|Author||Dr Paolo D.Avanzo|
|Description||IGR 0029+5934 is the 6th transient accreting millisecond X--ray pulsar (TAMP) discovered. In outburst and in quiescence TAMP are peculiar, showing faint outbursts, weaker quiescent luminosities and (when detected) lack of the soft component usually observed in other quiescent transients. Here we propose to observe the newly discovered IGR J00291+5934. This source is the fastest TAMP with a spin period of 599 Hz (and an orbital period of 2.5 hr). This source has been observed in quiescence following during its return to quiescence thank to a Chandra DDT proposal. These observations in quiescence found the source at different luminosity levels. Here we ask for three observations to investigate this variability, aiming at disentangling power law versus black body variations.|

|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.
