Abstract
X-ray bursters and galactic bulge x-ray sources, or the most luminous x-ray sources in the galaxy, are reasonably well constrained in their basic nature but not in their origin. We have suggested they may all have been produced by tidal capture in high density cores of globular clusters, which have now largely been disrupted by tidal stripping and shocking in the galactic plane. General arguments are presented for cluster disruption by the possible ring of giant molecular clouds in the Galaxy. Tests of the cluster disruption hypothesis are in progress and preliminary results are summarized here. The G-K star “companions” previously noted for at least 4 bursters have spectra (in the two cases observed) consistent with metal rich cluster giants. Several possibilities are discussed, including the formation of hierarchical triples in the dissolving cluster or in the galactic plane.
