|Title||Crust cooling of the neutron star in 1RXS J180408.9 342058|

|Description||We propose a 70 ks XMM-Newton observation of the neutron star in 1RXS J180408.9-342058 (1RXS J1804), a transient LMXB which underwent a virgul4.5 month accretion outburst in 2015. The neutron star in transient LMXBs may experience crust heating during the outburst and subsequent cooling in quiescence. Tracking the thermal evolution of the crust over time helps indicate the properties of neutron star matter. 1RXS J1804 has already been monitored for virgul480 days into quiescence and observations have indicated crust cooling. By observing the source further in quiescence more constraints on the neutron star crust physics can be obtained, in particular at deeper layers in the crust than currently possible for this source.|

|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.
