Nine X-ray sources in the globular cluster 47 Tucanae.

VERBUNT F. and HASINGER G.

Abstract (from CDS):

We analyze ROSAT HRI observations obtained from 1992 to 1996 of the globular cluster 47Tuc. Identifications of two X-ray sources with HD 2072 and with a galaxy, respectively, are used to obtain accurate (<2") positions of the X-ray sources in the cluster. We find possible optical counterparts, including the blue objects V1 and V2, for three X-ray sources in the core of 47Tuc, but note that the probability of chance positional coincidence is significant. One of the five sources previously reported by us to reside in the cluster core is found to be an artefact of misalignment between subsequent satellite pointings.
