Stars are key drivers of chemical evolution in galaxies, enriching the interstellar medium with elements produced over their lifetimes and at their death. However, significant uncertainties remain in our understanding of stellar nucleosynthesis, due to the complex multi-dimensional processes occurring in stellar interiors.
Stellar evolution models aim to describe the internal structure and nuclear burning that determine the production for individual stars. On the other hand, Galactic chemical evolution models can test these predictions against the observational data available. The interplay between these two approaches offers a unique opportunity to constrain the origin of chemical abundances in galaxies.
In this talk, I will present recent efforts to connect stellar models and Galactic predictions, with a focus on key observables such as carbon abundances and isotopic ratios. This approach can offer new constraints on the evolution of stars and their role in shaping the chemical history of galaxies.
