| Abstract: |
Recent spectroscopic studies of the detailed abundance patterns characterizing globular cluster stars are briefly reviewed. Guided by our current knowledge of nucleosynthesis as a function of stellar mass occurring in stars and supernovae, we then identify some interesting constraints that these combined observational and theoretical considerations impose on the nature and timescale of the early chemical evolution of the Milky Way globular clusters. We are led to the conclusion that the abundance patterns observed in the halo clusters are very likely a consequence of self-enrichment. A model for such self-enrichment is then presented. |
