SWIFT J1626.6-5156 is a Be/X-ray binary
Abstract
We report results from NIR spectroscopy of the optical counterpart to the hard X-ray transient SWIFT J1626.6-5156 (ATel #678, #679). The proposed infrared counterpart (2MASS J16263652-5156305, ATel #688, #713, #739) was observed in visiting mode at the European Southern Observatory on 2010 July 23 with the SofI spectrograph on the 3.5m NTT in La Silla, Chile (ESO proposal 085.D-0297A). The sky had thin cirri, the seeing averaged between 0.9'' and 1.3'' and the target was observed at airmass 1.12.
