| Abstract: |
Asymptotic Giant Branch (AGB) stars are important players in the chemical evolution modelling of galaxies, because they are major producers of several chemical elements and excellent tracers of the structure and star-formation activity of their parent galaxies. A few examples of the importance of AGB stars are presented in this review, together with a number of open problems affecting chemical evolution model predictions related to element enrichment by AGB stars: the evolution of 4He and Na in globular clusters, the evolution of 3He and carbon isotopes in the Galactic disk, and the evolution of N and O in different types of galaxies. The need for homogeneous and complete sets of yields is emphasized. |
