Abstract : We model stars in the 15-25 Solar Mass range, with light, medium, and high surface rotational velocities at different metallicities and explore the variability in different properties using the stellar modelling code MESA. We determine and list out the number of RSGs, BSGs and YSGs present at the end and quantitatively present the stellar and burning lifetime of the star and, the core masses during different steps of the evolutionary cycle. We also present the mass coordinates of various nuclear burning shells and the extent of convective and radiative zones. We find interesting results for extremely low metallicity models and observe that mass loss is more prominent for massive stars while rotational mixing is prevalent for lower mass stars.
