Properties of the MESA models of set 2, in which the heating profile is introduced continuously throughout the evolutionary trajectory. Top: stellar radius (left) and luminosity (right). The blue curve corresponds to the nonheated models. The orange and green curves correspond, respectively, to the heating profile of model 63 and a heating profile that is ten times larger. Bottom: proton-proton reaction rate power (left) and CNO reaction rate power (right). The blue curve corresponds to the nonheated models and its ordinate is on the right side of the plot and given in units of log(L_⊙). The orange and green curves correspond to the ratio of rates in the heated and nonheated models, with colors the same as in the top panels.
