Notes. MZAMS represents the initial mass of our models. τCHB and τCHeB represent, respectively, the duration of the core H-burning and the core He-burning phases. Mcc represents the maximum size of the convective core during core H-burning (CHB). MHexC in columns 5, 6, 8 and 9 refer to the size of the H-exhausted core at the beginning, at the end of core He-burning (CHeB), and just before and after the second dredge-up. MC − ign gives the internal mass point of C ignition. XSDU(C), XSDU(N) and XSDU(O) are surface abundances at the end of the second dredge-up. All masses are given in solar units. The end of CHB was taken when central H-abundance Xc(H) < 10−8. The beginning of CHeB was taken when LHe = 100 L⊙ and the end of CHeB was taken when central the He-abundance Xc(He) < 10−8.
