Radial profile of luminosities for the four models as indicated in each panel, corresponding to various fluxes: vertical enthalpy flux (L_h, dash-dot, blue), radiative flux (L_rad, long dash-dot, black), vertical kinetic energy flux (L_k, dot, red), convective heat flux (L_δT, dash, magenta). The total luminosity L_tot = L_h + L_rad + L_k (solid, green) is also displayed. Luminosities are divided by the luminosity of the corresponding model. The convective boundary corresponding to the Schwarzschild boundary from the 1D initial model is indicated by the vertical solid line.
