Very Massive Star Models: I. Impact of Rotation and Metallicity and Comparisons with Observations

Understand

In addition to being spectacular objects, Very Massive Stars (VMS) are suspected to have a tremendous impact on their environment and on the whole cosmic evolution.

• The nucleosynthesis both during their advanced stages and their final explosion may contribute greatly to the overall enrichment of the Universe.
• Their resulting supernovae are candidates for the most superluminous events and their extreme conditions also lead to very important radiative and mechanical feedback effects, from local to cosmic scale.
• We explore the impact of rotation and metallicity on the evolution of very massive stars across cosmic times.
