I have just read about a hypothetical mechanism that may work here:

if a Super Nova happens in a tight binary and sheds half of its mass, then even a spherical symmetric SN blow-up would leave the pair (a neutron star and a star) moving fast in opposite directions after their gravitational string got 2 times weaker and tore apart

Now the star, of 1 sun mass and enriched in Ca and other nucleosynthesis products of the SN, is just inside the shock bow at bottom right of the posted optical pic and of the X-rays Chandra's pic and of radio pic.
So the neutron star must be somewhere inside the other shock bow at top left of the X-rays Chandra's pic and of radio pic.
here is radio = red, X-rays = green and blue

thanX Jac
With time they will move angularily for an Earth observer and get identified :)
