Evolution of the parameters ζ, Eq. (25) (top) and Δ, Eq. (28) (bottom), with the effective temperature of the model along its evolution from the PMS to the RGB. To be conservative, the layer where Ω is maximum is considered for ζ and the layer where the gradient is maximum is chosen for computing Δ. For ζ, we used m = −1, since ζ is higher for prograde modes, while for Δ we considered m = 1 as no difference is found for m = −1 due to the fact that Ω ≪ ω where Δ is maximum.
