Abstract :
[en] There are currently only six known high mass X-‐ray binaries (HMXBs) that also exhibit MeV, GeV, and/or TeV emission ("gamma-‐ray binaries"). Expanding the sample of gamma-‐ray binaries and identifying unknown Fermi sources are currently of great interest to the community. Based upon their positional coincidence with the unidentified Fermi sources 1FGL J1127.7-‐6244c and 1FGL J1808.5-‐1954c, the Be stars HD 99771 and HD 165783
have been proposed as gamma-‐ray binary candidates. During Fermi Cycle 4, we have performed multiwavelength
observations of these sources using XMM-‐Newton and the CTIO 1.5m telescope. We do not confirm high energy emission from the Be stars. Here we examine other X-‐ray sources in the X-‐ray sources in the field of view that are potential counterparts to the Fermi sources.
