Yields from single AGB stars

TL;DR

This paper reviews the nucleosynthesis processes in single AGB stars, focusing on how mixing affects stellar yields, to better understand planetary nebulae composition.

Contribution

It provides an overview of AGB stellar evolution and discusses the stellar yields from models, highlighting the impact of mixing processes.

Findings

Mixing processes significantly alter envelope composition.

Stellar yields depend on AGB phase nucleosynthesis.

Implications for planetary nebulae composition.

Abstract

In order to understand the composition of planetary nebulae we first need to study the nucleosynthesis occurring in the progenitor star during the thermally-pulsing Asymptotic Giant Branch (AGB) phase. I present an overview of single AGB evolution, with an emphasis on the mixing processes that alter the envelope composition, followed by a discussion of the stellar yields available from single AGB stellar models.
