Champlane's Search For Quiescent High-mass X-ray Binaries
Abstract
The ongoing Chandra Multiwavelength Plane Survey has built a vast database of 15,000 serendipitous Chandra sources in archival ACIS pointings in the Galactic plane. With follow-up deep optical/nIR imaging and spectroscopy, we aim to constrain the Galactic population of low-luminosity (Lx<10^34 erg/s) compact accreting binaries. Here we present the results of a search for candidate high-mass quiescent X-ray binaries (qHMXBs). We have selected O/B counterparts to Chandra sources and examine their measured X-ray spectral hardness, X-ray variability, X-ray-to-optical flux ratio, and inferred distance and X-ray luminosity; in this way we identify 1 promising qHMXB candidate. We compare the properties of the likely isolated O/B stars to those known from earlier shallower (e.g. ROSAT) surveys.
