| Description | NGC 7793 P13 is one of the best targets among the ultra-luminous X-ray pulsars (ULXPs) to study how neutron stars can sustain accretion rates orders of magnitude above their Eddington limit. It has strong pulsations and a known optical counterpart, which allowed us to determine the full orbital ephemeris using XMM- Newton data. In 2020 P13 entered an off-state, from which it is currently re- emerging. This gives us the unique opportunity to study the accretion flow as the accretion geometry is changing and will allow us to infer more physical parameter of the system, like the magnetic field. Therefore we propose to continue our successful campaign of AOs 17 19 to monitor the spectrum and pulse period of P13 and other sources in NGC 7793 throughout AO 20 with 2 40 ks observations. |

| 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. |
