Comparison of the stellar envelope angular velocity evolution according to models KB (black solid line), MB (red dashed line), and GB (blue dot-dashed line) with observations. Mass scaling is corrected according to the MCMC fit for all models. The corresponding core angular velocity for each model is reported in gray with the same line style as for the envelope angular velocity. Dotted lines represent Eq. (19)(Skumanich law) with t₀ = 0.55 and t₀ = 2.50.
