Description SAX J1810.8-2609 is a neutron star LMXB transient with a very low quiescent luminosity. It is one of only three non-pulsars with evidence for only weak thermal quiescent emission, making it a prime source to test quiescent emission theories. Its quiescent emission is consistent with a pure power-law spectrum and does not require a soft (thermal) component, yet quiescent neutron star LMXBs are expected to have thermal emission associated with an accretion-heated surface. The lack of a thermal component would require the neutron star to be cooler than can be explained by current heating and cooling models and might require the designation of a new subclass of power-law-only quiescent transients. We propose to make a deep search for thermal emission from SAX J1810.8-2609.

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.
