Notes. The horizontal dashed line separates those models above it, in which enough material becomes unbound from the ONe core/WD that the remaining bound remnant has a mass below the effective Chandrasekhar limit MCh, from those below (i.e. the H series of models) which will collapse to form a neutron star. The quoted Fe masses are actually the sum of all the Fe-group elements. .

(*)

These diagnostics were calculated for H01 at t ≈ 330 ms, at which time the simulation was stopped because the maximum density reached ~1011 g cm-3, exhibiting clear signs of core collapse. Thus, for the H01 model is the mass of Fe-group elements in the core after ~330 ms
