ROSAT observations of ten globular clusters with large core radii.
JOHNSTON H.M., VERBUNT F. and HASINGER G.
Abstract (from CDS):
We present X-ray observations of ten globular clusters observed with the Rosat PSPC. The clusters were chosen to have large core radii and to be nearby. Three clusters contain X-ray sources which are probably associated with the cluster. One is the previously discovered X-ray transient H1825-331 in NGC 6652. The other two, in NGC 6366 and NGC 6809, are new members of the class of low-luminosity sources, with luminosities in the region of 1032erg/s. Upper limits can be placed on the source temperatures of both sources, making them similar to sources found in other globular clusters by Rosat .
