Notes. The computed models are based on the corresponding pre-SN models of Table 1, except for model N20-C, which has the same composition of metals as model N20-P with its hydrogen mass fraction enhanced to Xsurf = 0.735 at the expense of helium in the hydrogen-rich envelope. MCC is the mass of the collapsing core; Menv, the ejecta mass; Eexp, the explosion energy; , the mass of radioactive 56Ni produced directly in shock-heated ejecta by our reaction network; , the aggregate mass of directly produced 56Ni and tracer nucleus; and , the representative radioactive 56Ni mass containing the whole directly produced 56Ni and half of the tracer nucleus. and are the two moments at which the 3D simulations are mapped to a spherically symmetric grid. tSB is the epoch of shock breakout in the early-time 1D simulations.
