Possible optical counterparts to the X-ray point source in the supernova remnant CTB 80.
Abstract
A three color CCD image of the central region of the supernova remnant CTB 80 is presented, along with astrometry and photometry of many stars in the field. The color image does not show evidence of heavy or variable dust absorption in the surrounding region. Using an Einstein High Resolution Imager position for the central X-ray point source, two possible optical counterparts have been identified at magnitudes V = 19.9 and V = 20.9. Comparison of the intrinsic colors and magnitudes of these candidates are made to the optical properties of Crab and Vela pulsars, and they are found to be viable candidates.
