Recent observations of Galactic and extragalactic globular clusters have suggested that bright X-ray sources preferentially reside in metal-rich clusters. The same scenario may also happen for low-luminosity globular cluster X-ray sources. Although Chandra has observed many Galactic globular clusters, majority of them are metal-poor with [Fe/H]<-1 and there is no observational evidence for metal dependence. We propose to use Chandra/HST to study a sample of metal-rich ([Fe/H]>-0.5) globular clusters and to test the prediction that metallicity can affect the population of low-luminosity globular cluster X-ray sources.

We make use the high resolution images provided by HST to identify the nature of X-ray sources in globular cluster. We will cross-register the HST images, ground-based wide-field images, and Chandra images together for comparison.
