Notes. The quantities reported in the various columns are the initial mass of the star (Col. 1), the duration (Myr units) of the core hydrogen- (2) and helium-burning (3) phases, of the early AGB (4, kyr unit) and TP-AGB phases (5), and of the inter-pulse period (6), the highest luminosity (6, solar luminosity units) and temperature at the base of the convective envelope (7, Kelvin) attained during the AGB evolution, the highest value attained by the TDU parameter λ (9), the core mass (in solar masses) at the first TP (10) and at end of the AGB phase (11), the final surface C/O (12) and the fraction of the AGB lifetime during which the star has a C-star chemical composition (13).
