Absolute value for the mixed modes momentum flux normalised by the rotation rate (logarithmic scale) as a function of fractional radius for a 1.3 M_⊙ model high in the RGB. The original mixed modes flux computed using Eq. 14 is represented by the grey line. The modified mixed modes flux is represented by the orange line. The smaller panel shows a close up of the very central region of the star where the flux was modified.
