Core Concepts
Stochastic chemical enrichment from Population III supernovae explains both the observed scatter in CNO abundances in Milky Way halo stars and the exceptionally high C/O and N/O ratios in some distant galaxies, highlighting the critical role of these early stars in shaping galactic evolution.
