| Abstract: |
We use the grids of Geneva stellar evolution models and the new Population Synthesis Code (SYCLIST) to produce synthetic stellar populations, fully accounting for stellar rotation effects, and study their evolution in time. We show how the fraction of rapidly-rotating stars and of surface-enriched stars evolve with time and show how our theoretical results compare with some results in the literature for rotating populations, in particular with that of single Be stars. We propose to search among early B populations of the same age to look for differences in nitrogen enrichment effects. |
