| Abstract | NGC 7793 P13 is one of the best suited ultra-luminous X-ray pulsars to studysuper-Eddington accretion due to its easly detectable pulsations, when it isX-ray bright. In 2020/2021 it was in an off-state and no longer detected bySwift/XRT, but continued to spin-up, indicating continued high accretion.Currently the source is in an intermediate state, clearly detected by Swift/XRTbut below its historically maximum luminosity. In this state continuedmonitoring of the pulse period and spectral evolution is very interesting, as itallows us to investigate if there is any change in accretion rate or if allobserved variations are due to geometric effects. We propose to continue oursuccessful campaign to monitor P13 and other sources in NGC 7793 throughout AO 22 with 2x40 ks observations. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
