| Abstract: |
AGB stars are excellent laboratories to investigate
the nucleosynthesis and mixing processes occurring during the later
phases of the evolution of low and intermediate mass stars. The
determination of the abundances of several key elements in their
atmospheres – such as Li, CNO and their isotopic ratios, fluorine,
s-elements, etc. – is a key tool to constrain theoretical AGB
models. In this contribution, I briefly discuss some recent results
and current problems on this subject. |
