Title Soft X-Ray Transients in quiescence

Description Soft X-ray transient (SXT) behaviour is exhibited by both neutron-star and black-hole systems. While their outburst behaviour is very similar, the presence of an event horizon is believed to cause significant differences in their quiescent properties. However, current results are equivocal and it is essential to observe more systems with greater sensitivity. We therefore propose to observe 6 SXTs in quiescence, in order to quantify the luminosity difference between neutron-star-black-hole systems, so as to test the ADAF-ADIOS paradigm for accretion in quiescence.

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.
