Talk by Lee Anne Willson, ISU Physics and Astronomy Faculty

Planetary nebulae are formed in the remnants of a "superwind" that drives mass from stars near the end of their evolution as giants. What can evolutionary and mass loss modeling tell us about these winds, and how can observations be used to sort out the most successful models?
