Rotation period at the surface (black dashed line) and near the center (red line) of our fiducial 1.5 M_⊙ model (n_cv = 0) as function of its radius. The central rotation period of a similar model with n_cv = 2 is shown by the red dotted line. For comparison, the central rotation periods of models with no angular momentum transfer (green line) and with transfer due to the Tayler–Spruit dynamo (blue line) are also shown. Theoretical models are compared with the results of asteroseismic observations. Core rotation periods obtained by asteroseismic observations (Mosser et al. 2012; Gehan et al. 2018) are shown by the magenta dashed line. Surface and core periods obtained by Deheuvels et al. (2014) are shown by black and magenta pluses.
