Continued Tracking of the Spin of the ULX Pulsar NGC 7793 P13 with XMM-Newton

NGC 7793 P13 is one of the best targets among the ultraluminous Xray pulsars(ULXPs) to study how neutron stars can sustain accretion rates orders ofmagnitude above their Eddington limit. It has strong pulsations and a knownoptical counterpart, which allowed us to determine the full orbital ephemerisusing XMM Newton data. In 2020 P13 entered an offstate, from which it iscurrently re emerging. This gives us the unique opportunity to study theaccretion flow as the accretion geometry is changing and will allow us to infermore physical parameter of the system, like the magnetic field. Therefore wepropose to continue our successful campaign of AOs 17 19 to monitor the spectrumand pulse period of P13 and other sources in NGC 7793 throughout AO 20 with 2 40 ks observations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
