Abstract
In this manuscript, we present the one-dimensional stellar evolution of two rotating population III (Pop III) star models, each having a mass of 25M⊙ at the zero-age main-sequence (ZAMS). The slowly rotating model has an initial angular rotational velocity of 10% of the critical angular rotational velocity. In contrast, the rapidly rotating model has an initial angular rotational velocity of 70% of the critical angular rotational velocity. As an effect of rotationally enhanced mixing, we find that the rapidly rotating model suffers an enormous mass loss due to the deposition of a significant amount of CNO elements toward the surface after the main-sequence phase. We also display the simulated light curves as these models explode into core-collapse supernovae (CCSNe).
