Abstract We propose to extend our ongoing studies of the dynamical evolution of globular clusters by observing their populations of low-luminosity X-ray sources. Many of these sources are binary systems (or have evolved from them) and hold the key to the cluster's dynamical evolution. We propose observations of a variety of clusters with widely different physical properties such as central concentration, cluster size and mass, which are all key ingredients in the formation and evolution of binaries. To make this study as uniform as possible, the clusters will be observed to the same limiting luminosity. Joint observations with HST will allow for definitive source identification. ------------------------------------------------------------------------------------ 10349( 3) - 09/23/04 15:30 - [ 2] Observations Description ------------------------ ACS/WFC observations in B, r, andH-alpha will be taken in two globular clusters with 3 visibilities per cluster. (Clusters also to be observed with Chandra).
