Phyics of Very Massive Stars along the Cosmic History
I'm working on massive stellar evolution with the Geneva stellar evolution code GENEC, and I'm mainly focusing on the very massive stars, especially at very low and zero metallicity, where they might have been abundant. Apart from being spectacular objects, very massive stars (VMS) are also suspected to have a tremendous impact on their environment and, all in all, the whole cosmic evolution. The nucleosynthesis both during their advanced stages and their final explosion likely contribute greatly to the overall enrichment of the Universe. Their extreme conditions lead also to very important radiative and mechanical feedback effects, from local to cosmic scale.
