Abundances in giant stars of the globular cluster NGC 6752

Yong, David; Grundahl, Frank; Nissen, Poul E; Jensen, H.R.; Lambert, D.L.


Recent theoretical yields and chemical evolution models demonstrate that intermediate-mass AGB stars cannot reproduce the observed abundance distributions of O, Na, Mg, and Al. As a further observational test of this finding, we present elemental abundance ratios [X/Fe] for 20 elements in 38 bright giants of the globular cluster NGC 6752 based on high-resolution, high signal-to-noise spectra obtained with UVES on the VLT. This is the most complete spectroscopic analysis of this cluster in terms...[Show more]
