Core (continuous lines) and surface (dotted lines) rotation rates as a function of gravity for rotating models with different masses. Black, blue, and red lines indicate a mass of 0.75, 0.84, and 0.95 M_⊙, respectively. All models are computed with an initial velocity on the ZAMS of 2 km s^-1 and an additional viscosity of 3 × 10³ cm² s^-1 (ν_add is included during the whole evolution of the model). The red dot corresponds to the core rotation rate of KIC 7341231 (Deheuvels et al. 2012).
