Evolution of total angular momentum (top), surface specific angular momentum (middle), and rotational velocity (bottom) for a 20 M_⊙ Brott model with v_i = 300 km s⁻¹, which is ∼0.4 × v_crit. The dotted line indicates the original calculation, the solid line shows the value recalculated using the new angular momentum loss prescription. A 20 M_⊙ Geneva model (Eggenberger et al. 2021) is shown in gray in the top and bottom panels, with initial rotation set to 0.4 × v_crit.
