The Evolution of Stellar Rotation: Alone and Together, Inside and Out
Jamie Tayar, Assistant Professor, Department of Astronomy, University of Florida,

The rotation rates of solar-like stars on the main sequence depend on mass, metallicity, and binarity. As these stars evolve to the red giant phase, stellar winds, internal angular momentum transport, and interactions with other bodies can alter the surface and internal rotation rates further. In this talk, I will discuss current empirical constraints on the interior and surface rotation rates of evolved stars. I will also discuss how these results compare to stellar evolution models, and what constraints they can place on the physics of stellar rotation in general, as well as the history of individual stars in particular.
