We propose a moderately long ACIS-S observation of the nucleus of M31 in order to measure the structure of the only Bondi flow well resolved by Chandra, to search for eclipses in point X-ray sources, and to carry out a sensitive study of the structure of the diffuse gas and x-ray binary/SNR population in the core of M31. M31* recently entered a period of enhanced activity akin to Sgr A* flares, motivating our request for EVLA and HST/UV coverage. The proximity, high mass, and low ISM gas temperature of M31* give it the largest angular Bondi radius of of any SMBH. Thus it is the premier object for studies of SMBH sub-Eddington accretion. We will observe M31* using the COS/FUV/G140L grating. A total of four orbits will be divided in two epochs (visits), each with two orbits. In each epoch, simultaneous Chandra (50 ks with ACIS-S) and EVLA (20 hours with A-configuration) observations will be performed. 12 false 0.0 0.0 false false false false SUPPORTED GALAXY NUCLEUS J2000 J2000 COS/FUV Spectroscopic No No G140L The scheduling data was generated by CASM 20.0.
