Description The discovery of ultra-luminous X-ray pulsars (ULXPs), i.e., neutron stars
accreting orders of magnitude above their Eddington limit, raised the question
how these systems can become so bright. NGC 7793 P13 is one of the best systems
to study to find an answer to this question, because of its high flux, strong
pulsations and known optical counterpart. These properties allowed us to
determine the full orbital ephemeris using XMM-Newton. P13 also shows a
super-orbital period in the X-rays, the origin of which is currently unknown and
cannot be constrained with the existing data. Therefore we propose to continue
our successful monitoring campaign of the spectrum and pulse period of P13
throughout AO 19.

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.
