A photometric and spectroscopic study of the stellar populations in the Large Magellanic Cloud

摘要

In the last years we started a long-term project devoted to obtain a complete photo-metric and spectroscopic screening of the stellar populations of the LMC globular cluster system and surrounding fields. The ultimate goals of this project are as follows: .The definition of reliable and homogeneous cluster metallicity and age scales from high quality, high resolution spectra and color-magnitude diagrams. .The detailed study of the chemical abundance patterns of iron-peak, alpha-, s- and r-process elements, in order to constrain the star formation and chemical enrichment timescales of both the cluster and field populations and check for possible self-enrichment in the clusters.
