Radial profiles of a 4 M_⊙star from the Péclet grid with a central hydrogen content X_c = 0.5. The top panel shows the temperature gradients and the mean molecular weight per gas particle (μ). The middle panel shows the Brunt-Väisälä frequency (N), as well as the shape of the mixing profiles, divided in convective core (grey), near-core mixing (blue), and diffusive mixing in the outer radiative envelope (green). The bottom panel shows the mode inertia of two g modes with different radial orders. All dashed lines and transparent colours correspond to a model with the maximum amount of mixing included in our grid (α_CBM = 0.3,  f_CBM = 0.03,  log(D_env) = 4), whereas the solid lines and darker colours correspond to a model with a considerably lower amount of mixing (α_CBM  =  0.1,  f_CBM  =  0.01,  log(D_env)  =  1).
