Table 1: Selected features of the evolution of massive intermediate-mass stars prior to carbon ignition. The quantities shown are: the maximum extent of the convective core during the central hydrogen ( $M_{\rm HB}$ ) and helium ( $M_{\rm HeB}$ ) burning phases, the mass coordinate of the base of the convective envelope at its deepest extent during the first dredge-up ( $M_{\rm 1DUP}$ ), the mass of the CO core at carbon ignition ( $M_{\rm COi}$ ), the durations of central hydrogen ( $\Delta t_{\rm HB}$ ) and helium ( $\Delta t_{\rm HeB}$ ) burning phases, the time elapsed between the end of central helium burning and carbon ignition ( $\Delta t_{\rm HeB-CB}$ ) and the central $^{12}{\rm {C}}$ and $^{16}{\rm {O}}$ mass fractions at the end of He core burning. Masses are in solar unit ( $M_{\odot }$ ), times in years (yr). $M_{\rm COi}$ is defined as the mass coordinate of maximum nuclear energy production in the He burning shell.
