Movie available online showing the evolution of a system forcing frequency (red dot) including the effect of dynamical tidal on the stellar rotation ((dΩ_rot/dt)_tides, given on the y-axis) for a prograde mode (ℓ = 2, m = −2, k = 2, n = 20, Ω_rot = 0.05 Ω_crit). The red curve gives 1/m dσ/dt − (dΩ_rot/dt)_evo, which corresponds to the possible locking positions. Blue segments represent unstable mode regions; orange curves represent stable regions. The animations starts on the right of the resonance locking position identified in Fig. 1.
