|Title||Be-X-ray Pulsars in Quiescence|
|Author||Dr Peter Kretschmar|
|Description||We propose to observe several transient Be-X-ray binary pulsars in quiescence. While these sources have been extensively studied during outbursts, little is know about their behaviour at low luminosities. There is a disctinct chance to observe centrifugal inhibition of accretion - the so-called propeller-effect. If this is not observed, significant insight can be gained into the accretion and emission geometry by comparing these results with those obained while the sources were much brighter. The sources we propose to observe are A0535+262, V0332+53 and A0538-66.|

|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.
