Globular Clusters, Element Abundances

Scientific paper

We compare the correlations of O with Na and Na with Mg among halo field stars with corresponding correlations among giants in the globular clusters M13 and M3. These clusters have nearly the same metallicity which is close to the peak of the halo metallicity distribution. The morphology of their color-magnitude diagrams illustrates the so-called second parameter effect. The halo field giants and dwarfs show similar O vs Na and Na vs Mg relations and thus the observed correlations are not a function of stellar evolution. In the clusters the correlations are remarkably different from those of the halo field stars and the clusters in turn differ from one another. Implications of these results in the controversy over primordial vs evolutionary effects on the abundances of globular cluster stars will be discussed.
