Spectral type


Swift J174540.2-290005 is 1 pc from Sgr A* assuming an 8.5 kpc distance ( Kennea2006 ). If this transient is an X-ray binary it would be a LMXB ( Wang2006 ). VLA observations did not detect a radio counterpart leaving open the possibility of magnetar or a LMXB hosting a NS or BH ( Bower2016 )
