We request 35 ks with EPIC to compliment a 200 ks depth 10-30 keV NuSTAR surveyof an area of the M31 disk. These simultaneous XMM-NuSTAR observations will alsocompliment previous XMM-Newton wide-field and XMM/Chandra bulge-monitoringstudies of M31. We will measure the 0.5-30 keV spectra of the X-ray Binaries(XRBs) detected by XMM and NuSTAR (reaching 3e36 erg/s, 4-25 keV) therebyconstraining the accretion states of hard X-ray point sources and compare themwith well-studied Galactic XRBs.

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.
