Abstract

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 first reported IR flux values. In common with many other similar systems, the results show the presence of a strong, frequently variable IR signal. The implications of some of the results are discussed.
