Description Quiescent X-ray transients provide a superb laboratory for investigating the properties of the residual accretion flow onto their neutron star (NS) and black hole (BH) compact objects. It has been claimed that the presence of an event horizon causes a significant difference in their quiescent behaviour. However, current results are equivocal as there are a variety of factors which can complicate the NS behaviour as well as determining whether their mass transfer rates really are similar. It is therefore essential to observe NS systems with greater sensitivity. Our proposal is to observe 4 NS transients in quiescence, in order to quantify the luminosity difference and properties of these two classes of SXTs.

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.
