Abstract: |
Galactic globular clusters are known to have multiple stellar
populations with different scenarios being debated for their origin.
In this context, the core of our project is to disentangle the
first and second generation stars based on their chemical properties,
in order to test different model predictions. Here we present a
preliminary chemical analysis of a new sample of AGB stars in
NGC 2808 observed at the VLT with FLAMES, in order to further
investigate the recent finding that no Na-rich stars are found
on the AGB. |
