"Chemical inhomogeneities in Globular Cluster stars and the multiple population puzzle(s)"
Abstract. Our view of Globular Clusters has fundamentally changed in the last decade. Modern spectroscopic and photometric data have revealed the inadequacy Simple Stellar Population, shifting the paradigm to that of Multiple Populations and reopening the issue of the formation of such objects. The study of light elements abundances in stars at different evolutionary stages provide crucial information for the understanding of the formation process of Globular Clusters. I will present the latest results from our multi-instrument optical and infra-red spectroscopic survey of Globular Clusters, and discuss their implications for the disentangling of the multiple population puzzle(s).
