General Description

The main aim of this proposal is to observe a sample of BHB stars in
the Globular Clusters NGC6752 and M4 using UVES spectrograph. The final
goal is to study the detailed chemical composition of these HB stars in the
context of chemical inhomogeneities in GCs.
The secondary aim is to a sample of stars from the TO up to the RGB tip
using GIRAFFE spectraograph, with the goal of study the evolution of superficial
 
light element abundances in the context of the stellar evolution theory.
