Title Tracking the Neutron Star ULX NGC 7793 P13 with XMM-Newton to Measure its Orbit

Author Dr Felix Fuerst
Description Following a series of remarkable 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 currently known: M82 X-2, NGC 7793 P13, and NGC 5907 ULX1. Here we propose two short XMM-Newton observations of P13 to follow-up on our successful campaign in AO 16, to track the evolution of the pulse period, to confirm the orbital ephemeris, and to monitor the X-ray spectrum. P13 is the ideal source for this program, as it is the ULX pulsar in which the pulsations are most clearly detected and the only one for which the companion star is well known, allowing us to fully quantify the orbit and measure the inclination through X-ray timing.

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.
