The ages of 55 globular clusters as determined using an improved method along with color-magnitude diagram constraints, and their implications for broader issues

VandenBerg, Don A.; Brogaard, Karsten; Leaman, R.; Casagrande, Luca

Description

Ages have been derived for 55 globular clusters (GCs) for which Hubble Space Telescope Advanced Camera for Surveys photometry is publicly available. For most of them, the assumed distances are based on fits of theoretical zero-age horizontal-branch (ZAHB)
