Table 2
Pre-SN progenitor properties for our model set. MH,e refers to the H-rich envelope in the type II SN models.
| Model | Mtot | MH,e | MHe,c | MCO,c | MSi,c |
|---|---|---|---|---|---|
| Type II SN progenitors | |||||
| m12 | 12.4(a) | 9.0 | 3.4 | 1.9 | 1.6 |
| m15 | 13.5 | 9.0 | 4.5 | 2.8 | 1.75 |
| m20 | 15.9 | 9.0 | 6.9 | 4.9 | 2.0 |
| m25 | 18.3 | 9.0 | 9.3 | 7.1 | 2.3 |
Notes. The He, CO, and Si core masses correspond to Lagrangian masses. (a) The type II SN model m12 has a total mass greater than the initial mass by 0.4 M⊙ because of the adopted H-rich envelope mass. Its core properties are, however, compatible with the results from our MESA grid. Such a model couldarise from a merger (Menon & Heger 2017).
