\caption{Ignition  density  and  maximum central  temperature  reached
         during the  captures on $^{24}$Mg and  $^{24}$Na, for several
         initial  abundances of  $^{24}$Mg.  The  cases  whose central
         densities   are  marked  with   an  asterisk   correspond  to
         off-centre  explosions. In all  the calculations,  the Ledoux
         convective criterion has been adopted.}
