Stellar Wind Yields of Very Massive Stars

Understand

The most massive stars provide an essential source of recycled material for young clusters and galaxies.

• While very massive stars (VMS, M>100M) are relatively rare compared to O stars, they lose disproportionately large amounts of mass already from the onset of core H-burning.
• VMS have optically thick winds with elevated mass-loss rates in comparison to optically thin standard O-star winds.
• We compute wind yields and ejected masses on the main sequence, and we compare enhanced mass-loss rates to standard ones.
