TL;DR
This paper reviews how chemical differences in multiple stellar populations within globular clusters influence their evolution and spectral properties, providing a theoretical framework for interpreting these complex systems.
Contribution
It offers a novel theoretical framework to understand the evolutionary effects of multiple populations in globular clusters.
Findings
Chemical peculiarities affect stellar evolution and spectra.
Second generation stars show distinct evolutionary signatures.
Framework aids in interpreting observational data.
Abstract
We briefly summarize the impact of the chemical peculiarities associated to the multiple population phenomenon in Galactic Globular Clusters, on the evolutionary properties and spectral energy distribution of second generation stars, in comparison with the primordial stellar component.
