The X-ray binary X2127+119 in M15: evidence for a very low mass, stripped-giant companion
We present integral field spectroscopy of X2127+119, the luminous X-ray binary in the globular cluster M15, obtained with INTEGRAL/WYFFOS on the William Herschel Telescope. We find that tomograms of HeIIλ4686 line profiles appear to be incompatible with the previously assumed view of X2127+119, in which the binary consists of a 1.4-Msolar neutron
