In early-type X-ray faint (lowest LX/LB) galaxies, Chandra has resolved most of the X-ray emission into point sources, dominated by low-mass X-ray binaries (LMXBs). Studies of these LMXBs, such as the AO-1 observation of NGC 4697, are yielding some understanding of the LMXB populations in early-type galaxies, their relations to globular clusters, their histories of star formation, and comparisons to spiral galaxies; however, deeper observations are required to detect the more numerous, fainter LMXBs. To that end, I present initial results of multiple, deep observations of NGC 4697, the nearest, optically luminous, X-ray faint, elliptical galaxy with a large GC population.
Support for this work was provided by the National Aeronautics and Space Administration through Chandra Award Number GO4-5093X, issued by the Chandra X-ray Observatory Center, which is operated by the Smithsonian Astrophysical Observatory for and on behalf of NASA under contract NAS8-39073.
