Confirming the compact X-ray binary in a new supernova remnant G308.3-1.4
Abstract
We have identified a central compact object (CCO) in the newly identified supernova remnant G308.3-1.4. An interesting periodicity candidate of 1.4 hours has been found in a short exposure by Chandra. Together with its flux variability, this object resembles the well-known CCO associated with RCW 103. However, different from the case in RCW 103, optical/IR counterpart of the CCO in G308.3-1.4 is unambiguously identified and its spectral energy distribution suggests it as a promising compact binary candidate. We propose a XMM-Newton observation to confirm the nature of this object so as to search for the direct evidence of a compact binary survived in a supernova.
