| Description | We propose to continue our highly successful coverage of the cooling neutron star in MAXI J0556-332, which was strongly heated during a near/super-Eddington outburst in 2011/12 and again during a smaller outburst in 2016. Our quiescent observations, which revealed an extraordinarily hot and rapidly cooling neutron star, have provided unique insights into neutron-star structure and in particular into the nature of heat sources in the shallow outer crust. Recent observations suggest that the ongoing cooling trend is now dominated by heat induced during the first outburst in deeper crustal layers. We request a 106 ks XMM-Newton observation to investigate if the remarkable properties of the outer crust extend to deeper layers where matter reaches nuclear density. |

| 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. |
