| Description | Following a series of remarkable recent discoveries, we now know that some of the most luminous members of the ultraluminous X-ray source (ULX) population are actually powered by apparently super-Eddington neutron star accretors. Three such systems are now known: M82 X-2, NGC7793 P13, and NGC5907 ULX1. Here we propose a series of XMM-Newton observations of P13, two of which will be coordinated with NuSTAR, in order to track the evolution of the pulse period, test the proposed orbital nature of the 64d optical period, and investigate changes in both the average and the pulse-phase resolved emission as a function of flux, for comparison with the broader ULX population. Out of the three ULX pulsars currently known, the low absorption and lack of source confusion make P13 the ideal candidate for this study. |

| 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. |
