Saturation time as a function of initial rotation rate Ω₀. To calculate each rotation track, we fit power laws to the core-envelope coupling timescale and disk-locking timescales for our 10th, 50th, and 90th percentile models of and , where the timescales are given in Myr and Ω₀ is in solar units. The dashed line shows our best fit, given by Eq. (2), and the vertical lines show the saturation times of the 10th, 50th, and 90th percentile rotators.
