The next step is to follow the evolution of individual element abundances, which can trace the relative importance of different types of stars to the galactic chemical enrichment. Indeed, first empirical models resolved in alpha-elements (excessively produced by super novae type II) are becoming available (Walcher et al 2009, Prugniel & Koleva 2012, Vazdekis et al in prep). Before applying them to distant galaxies, the first necessary step will be to test them with near-by resolved and known systems as the Galactic Globular Clusters. Here, we use the library of Schiavon et al 2005 to test these models and indicate their successes and pit-falls. |
