Abstract
The prospect of precise, rotation-based stellar ages drives the development of magnetic braking models for Sun-like stars. The vast majority of these magnetic braking laws have been calibrated on and for main sequence stars. While rotation-age relations lack the same utility on the subgiant branch, subgiant rotational behavior remains an excellent test of the underlying stellar evolutionary models and the magnetic braking prescriptions themselves. I will extend two different main sequence braking models onto the subgiant branch: a “standard” model in which angular momentum loss occurs smoothly over the entire main sequence, and the more recent “weakened” magneti...
