Notes. The columns show the initial mass (1), the maximum extent of the convective He-burning core (2), the mass at core helium depletion (3), the maximum mass of the CO core (4), the time between core C-ignition and the end of the run (5), the maximum radius exhibited between core He-depletion and 20 kyr before the end of the run (6), 10 kyr (7), 5 kyr (8), 1 kyr (9), 1 yr (10), and the absolute maximum value (11). Columns 12–14 show the central density, central and maximum temperature in the model at the end of the run respectively. Column 15 highlights the burning phase at the end of the run labeled according to the nuclei being burnt, if it didn’t reach CC because of numerics. ^(*)Models have experienced a strong expansion of the envelope before terminating (see Sect. 3.1). (EC) The lowest-mass model is expected to end as an EC-SN.
