Main-Sequence and sub-giant stars in the Globular Cluster NGC6397: The complex evolution of the lithium abundance
J. I. González Hernández, P. Bonifacio, E. Caffau +6
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 (MS) stars of a Globular Clu…

Lithium in the Globular Cluster NGC 6397: Evidence for dependence on evolutionary status
J. I. Gonzalez Hernandez, P. Bonifacio, E. Caffau +6
Most Globular Clusters are believed to host a single stellar populations. They can thus be considered a good place to study the Spite plateau and probe for possible evolutionary mo…

Lithium abundances of Main Sequence and Sub-Giant stars in the Globular Cluster NGC 6397
J. I. González Hernández, P. Bonifacio, E. Caffau +6
We present FLAMES/GIRAFFE spectroscopy obtained at the Very Large Telescope (VLT). Using these observations we have been able for the first time to observe the Li I doublet in the…
