|Title||The Nature of Quiescent Emission from Soft X-ray Transients|
|Author||Dr Martin Turner|
|Description||GT-We propose to observe a sample of soft X-ray transients in order to understand the mechanism responsible for the quiescent emission. The different proposed models include accretion (down to the ns surface or stopped at the magnetospheric radius), shock emission from a relativistic pulsar wind, thermal emission from a cooling ns. Detailed spectral information capable of discriminating among the above models can only be provided with EPIC for these weak sources.|

|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.
