Two $2.0~M_{\hbox{$\odot$ }}$ models are solved at different evolutionary phases, with a MLT parameter $\alpha =1$ and the CEFF equation of state. Different values correspond to different locations of the connecting layer: $\tau =1,1.1,1.2,1.3$ . "+'' are for the model with $X_{\rm c}=0.25$ and " $\times$ '' for $X_{\rm c}=0.55$ .

A model of a $1.8~M_{\hbox{$\odot$ }}$ is solved with $X_{\rm c}=0.44$ , a MLT parameter $\alpha =1$ and the CEFF equation of state. Results obtained "with'' (+) and "without'' atmosphere ( $\times$ ) in the non-adiabatic treatment are compared.

Models of $1.8~M_{\hbox{$\odot$ }}$ are solved with $X_{\rm c}=0.44$ and with different values for the MLT parameter: $\alpha =0.5,1,1.5$ . Note the sensitivity of the non-adiabatic results with respect to $\alpha$ .

Note the differences appearing in the superficial convection zone as $\alpha$ values rise.
