Title: New Line-Blanketed Model Atmospheres and their Impact on Evolutionary Synthesis Models.

Abstract:

A new grid of non-LTE, line-blanketed model atmospheres for O and Wolf-Rayet stars has been developed to provide realistic ionizing fluxes for evolutionary synthesis models of young starbursts. We find significant differences in the ionizing fluxes compared to previous work, particularly during the WR phase of a starburst. The implications of these new models for starburst properties will be discussed.
