X-rays from the brightest globular cluster of M31

We propose to observe G1 (Mayall II), the brightest and most massive globular cluster of M31. It is an extremely dense and massive globular cluster, an excellent target in which to search for a bright Xray source. ROSAT did not observe it. The primary goal of our proposal is to determine whether G1 contains an Xray source, as a pilot observation for a later proposal. If the source is bright we can make a preliminary spectral classification (neutronstar vs. black hole binary) and a preliminary search for orbital variation.It is interesting for theory to know whether this extremely dense clustercontains a bright source; and also which fractions of bright sources areneutronstar binaries and blackhole binaries. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
