I discuss stellar spectroscopy and nucleosynthesis. Astronomers recognize two distinct episodes of nucleosynthesis, primordial (big bang), and stellar. Nucleosynthesis has been invoked to explain the chemical abundances found in the universe. I particularly discuss stellar nucleosynthesis, through the proton-proton chain, the CNO cycle, the triple alpha process, the r process and s process. Astronomers have developed an elaborate, physically robust evolutionary theory to explain the abundances that we see throughout the universe. While this theory may be explanatory, it has no predictive power. A creationary theory of the chemical abundances that we see in the universe is most desirable.
