Globular clusters and primordial composition.
Abstract
The primordial chemical composition and the abundance of the primordial elements in globular clusters, specifically in population II, are reviewed. Timetables of the big bang and of important events during the nucleosynthesis period are presented, and the predicted primordial abundances in the big bang are examined. The abundances of He-3 and He-4, D, and Li; the metallicity of clusters; and the abundance ratios in globular-cluster stars are discussed.
