Title: How stellar winds affect stellar evolution

 Abstract: I will begin with a brief review of the different mechanisms by which stars lose mass. I will then describe how stellar winds influence stellar evolution across the H-R diagram. I will mention the effect of stellar winds as they relate to galactic chemical evolution.

Title: The Revolution Revolution: towards a complete stellar spin-down model

Abstract: Detailed MHD stellar wind models have demonstrated that surface magnetic field topology has a strong influence on wind-driven angular momentum loss. Observations suggest that faster rotating stars store a larger fraction of their magnetic flux in higher order components of the magnetic field. In this talk I will discuss how a magnetic complexity that evolves from complex toward simple configurations as a star spins down can explain the salient features of stellar rotation evolution, including the bimodal distribution of both slow and fast rotators seen in young open clusters.
