| Description | We propose to complete our deep homogeneous survey of M31 down to a limiting point source luminosity of 10E35 erg-s which will include all active XRBs. M31 is a milestone project for X-ray astronomy. Given its proximity it is the ultimate target for a detailed X-ray inventory of an archetypal low-star-formation-rate galaxy like our own. We will study M31 XRBs and GC sources, SSSs, SNRs and the hot ISM in contrast to fore- and background objects. The observations will provide high quality spectra and light curves, allowing source classification and modelling of their SED. The population characteristics of HMXBs and LMXBs will provide independent constraints on the star formation history of M31, the LG in general, as well as constraints on the formation channels of compact objects. |

| 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. |
