Abstract | We propose a 70 ks XMM-Newton observation of the neutron star in 1RXSJ180408.9-342058 (1RXS J1804), a transient LMXB which underwent a ~4.5 monthaccretion outburst in 2015. The neutron star in transient LMXBs may experiencecrust heating during the outburst and subsequent cooling in quiescence. Trackingthe thermal evolution of the crust over time helps indicate the properties ofneutron star matter. 1RXS J1804 has already been monitored for ~480 days intoquiescence and observations have indicated crust cooling. By observing thesource further in quiescence more constraints on the neutron star crust physicscan be obtained, in particular at deeper layers in the crust than currentlypossible for this source. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
