\caption{\label{tab2}Radius and central thermodynamic properties of a planet of mass $M_{\rm P}=1~\mjup$ at 1~Gyr for two 
 heavy element mass fractions $Z=(M_Z/M_{\rm P})=50$\% and $Z=20$\%. The labels are the same as in Table~\ref{tab1}. As mentioned at the end of Sect.~4.2, for $Z=50$\%, the solution with $\mcore=0$ and $Z=\zenv$
 is similar to a solution with $\mcore \sim 10~\mearth$ and the rest of the heavy material distributed in the
 envelope.}
