The Chandra survey of the SMC "Bar". II.
Listed in IVOA Registry (Virtual Observatory)
We present the most likely optical counterparts of 113 X-ray sources detected in our Chandra survey of the central region of the Small Magellanic Cloud (SMC) based on the OGLE-II and Magellanic Clouds Photometric Survey catalogs.
Description
We estimate that the foreground contamination and chance coincidence probability are minimal for the bright optical counterparts (corresponding to OB type stars; 35 in total). We propose here for the first time 13 high-mass X-ray binaries, of which four are Be/X-ray binaries (Be-XRBs), and we confirm the previous classification of 18 Be-XRBs.
We estimate that the new candidate Be-XRBs have an age of ~15-85Myr, consistent with the age of Be stars.
