摘要
We present first results of a campaign to find and identify new compact objects in the Galactic center. Selecting candidates from a combination of Chandra and 2MASS survey data, we search for accretion disk signatures via infrared spectroscopy. We have found the infrared counterpart to the Chandra source CXO J174536.1-285638, the spectrum of which has strong Br gamma and He I emission. The presence of C III, N III, and He II indicate a binary system. We suspect that the system is some form of high-mass binary system, either a high-mass X-ray binary or a colliding-wind binary.
