Evolution of the rotation rate for an initially slow (lower red curves) and fast (upper blue curves) rotating solar-mass star, for different disc lifetimes: τ_d = 1 Myr (solid curves); τ_d = 5 Myr (dashed curves); τ_d = 10 Myr (dotted curves). The solar value is indicated by a solid circle. Direct and inverted triangles are observational data compiled in Table 1 of Bouvier (2008) and represent respectively the 10th and 75th percentiles of observed rotational period distribution.
