High mass X-ray binaries (HMXBs) that also produce very high energy radiation on the order of MeV–TeV (?-ray binaries) are a rare and interesting class of objects: only four such objects have been discovered to date. We have obtained optical spectra from several of these objects in the past year, including a new source just discovered in the fall of 2008. We present an analysis of these optical spectra as part of a multi-wavelength campaign to study the stellar/companion interactions and determine the mechanism producing the high energy emission.
