Description
Stars are the primary drivers of chemical enrichment in galaxies, producing elements throughout their lives and releasing them into the interstellar medium. However, uncertainties in stellar evolution and nucleosynthesis remain a major challenge for understanding the origin of the chemical abundances observed, particularly in metal-poor stars and early stellar populations.
Stellar evolution models describe the internal structure and nuclear burning of individual stars, providing predictions for the elements and isotopes they produce. Galactic chemical evolution models, in turn, can test these stellar yields, allowing theoretical predictions to be confronted with observations.
In this talk, I will present recent work exploring the connection between stellar modelling and Galactic chemical evolution, with a focus on metal-poor environments and the chemical signatures of early stellar populations. I will discuss how stellar nucleosynthesis predictions can help interpret elemental abundances and isotopic ratios, and how these observables can provide insights into stellar evolution and the chemical history of galaxies.
