Abstract

Duplicity is important to our understanding of stellar nucleosynthesis. Binary systems open up nucleosynthetic pathways to produce isotopes that are not easily produced in other ways. In addition, the less evolved companions of binary stars can preserve a chemical record of the nucleosynthesis of their long-dead partners. Using the specific case of carbon-enhanced metal-poor stars, I will discuss nucleosynthesis in asymptotic giant branch stars and how our inferences are affected by what happens to material accreted by the companion.
