Analysis of Star Formation Rate Variations in the Interstellar Medium Influenced by Stellar Generations and Metallicity
Year: 2025
Type: dissertation
Abstract: This thesis investigates the chemical evolution of early stellar populations, focusing on the metallicity of mixed remnants from first and second-generation stars. Through quantitative calculations, we demonstrate that even with a substantial contribution of metal-free ejecta from Population III supernovae, the resulting mixed interstellar medium retains a low metallicity characteristic of Population II star formation environments. This finding supports the classification of stars forming from such mixed material as second-generation, furthering our understanding of the transition from primordial star formation to the metal-enriched stellar populations observed in the Universe today. Our analysis draws upon established literature values for stellar population metallicities and star formation contexts to provide a robust framework for interpreting these evolutionary processes.
