| Description | We propose to continue our very successful program to use the observed cooling of the crusts in transiently accreting neutron star X-ray binaries to probe the behavior of ultra-dense matter. Those crusts are heated due to the accretion of matter during the outbursts of those transients. After the outbursts are over the crusts cool until they are in equilibrium with the cores again. Following this cooling process for several systems has given us important insights in the structure of neutron stars, but many uncertainties remain. Therefore it is needed to enlarge our sample to obtain better insights in the behavior of how neutron stars react to the accretion of matter. Our program combines the strengths of Chandra and XMM-Newton and has proven to be excellently suited to obtain those goals. |

| 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. |
