Heavy element abundances in AGB stars. II. 47 Tucanae

This research forms the second part of an investigation into heavy element abundances in Asymptotic Giant Branch (AGB) stars in different stellar environments. High resolution spectroscopy was taken of seven known AGB stars in 47 Tucanae and spectrum synthesis undertaken to obtain abundances for s-process elements. Contrary to theoretical predictions, preliminary results show that these AGB stars do show s-process enhancements relative to previously studied Red Giant Branch (RGB) stars in the same cluster.
