Abstract
Large inter- and intra-cluster abundance variations of several light elements are observed among Galactic globular cluster stars. Correlations among these abundances suggest that many of the chemical inhomogeneities have been caused by high temperature advanced proton-capture fusion reactions. The evidence for this proton-capture reshuffling is addressed, along with comments on possible sites for this nucleosynthesis.
