| Abstract: |
The stellar winds from massive stars in clusters can return significant amounts of mass, energy, and enriched material to the surrounding ISM. I discuss a new grid of non-LTE models for O and W-R stars, developed at UCL, which provides a new set of stellar wind parameters and realistic ionizing fluxes for five metallicities. The wind parameters of both O and W-R stars are scaled with metallicity Z. The new models are compared with those available in Starburst99. The rates of mass and energy return from young massive clusters are found to be significantly different from the previous predictions of Leitherer, Robert & Drissen (1992), particularly during the Wolf-Rayet phase at low metallicity. The amount of enriched material released from W-R winds is predicted to be much lower at metallicities below solar because of the mass loss scaling. |
