Main-sequence and sub-giant stars in the globular cluster NGC 6397: The complex evolution of the lithium abundance

Résumé

Thanks to the high multiplex and efficiency of Giraffe at the VLT we have been able for the first time to observe the Li I doublet in the Main Sequence stars of a globular cluster. At the same time we observed Li in a sample of Sub-Giant stars of the same B-V colour.
