Near-IR photometry of southern X-ray binary systems

1997

We report IR measurements of 30 optical counterparts to a group of possible and probable High Mass X-ray Binaries (HMXRBs). In the majority of the systems these measurements represent the rst reported IR flux values. In common with many other similar sys- tems, the results show the presence of a strong, frequently variable IR signal. The implications of some of the results are discussed.
