Title: Spectroscopic confirmation of a compact binary system within a supernova remnant
Abstract: We propose to observe the central compact object (CCO) of the supernova remnant G308.3-1.4 with Gemini-S to reveal the nature of the object. From the X-ray data, we found a 1.4-hr periodicity, and by combining with the X-ray spectrum as well as the optical spectral energy distribution, we suggest that the source is an X-ray binary system. We propose to obtain an optical spectrum with Gemini-S/GMOS to investigate the nature of the optical emission and the results will provide the first direct evidence for an accreting binary as a CCO.
