Abstract
The problem of the galactic globular cluster ages is revisited, discussing the possible sources of errors and indeterminations. The role of RR Lyrae variables is discussed in the frame of the evolutionary scenario. Application of a general fitting procedure to the galactic globular clusters M15 and M4 gives respectively t = (13±3)×109yr and t = (12.2±0.2)×109yr. A similar age for the globular cluster M3 is also suggested.Similar Articles
