Description Observing the cooling of neutron stars reheated by accretion provides unique in- sights into neutron-star structure. Here we propose to continue our observations of the cooling neutron star in MAXI J0556-332, a transient that had been accre- ting at near-super-Eddington rates for 16 months when it returned to quiescence in May 2012. XMM and Chandra observations in quiescence have revealed a rapidly cooling neutron star with by far the highest temperatures observed to date for such systems. We request an 80 ks XMM observation of MAXI J0556-332 to investi- gate if the current rapid cooling starts evolving into a temperature plateau. Knowing when and at what temperature this occurs will help us in understanding the properties of the neutron-star crust, as we start probing its deeper layers.

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.
