Evolutionary tracks for different masses and different α_CGM (left: 0.6; center: 0.7; right: 0.8). H–R constraints (L and T_eff) are shown with the blue box, and models satisfying the seismic constraints are shown with coloured points (cyan indicates models having a compatible ν_max, magenta a compatible  ⟨ Δν ⟩ , and orange models satisfying both conditions). Models with higher values of α_CGM shift compatible masses to lower values (see text).
