Rotation profiles given by Eqs. (8)–(10) at ZAMS for a 1.5 M_⊙ model for three different initial rotation ratios between convective core and surface of Ω_surf/Ω_cc = 1, 2, and 3 (dot-dashed, dashed, and solid lines, respectively). The bullets shown on the rotation profiles show the location where the angular velocity is equal to the mean value of the g-mode cavity computed with Eq. (6).
