Abundance ratios of Mg, Fe, Si, and C for SN 2018xx and SN 2019gbx.
| SN | SN 2018xx | SN 2019gbx |
|---|---|---|
| Mg | 0.144 ± 0.026 | 0.134 ± 0.028 |
| Fe | 0.130 ± 0.031 | 0.131 ± 0.035 |
| Si | 0.117 ± 0.030 | 0.119 ± 0.032 |
| C | 0.039 ± 0.009 | 0.030 ± 0.007 |
Notes. Elemental abundance ratios were normalized to one. The fit also includes 19 other elements: N, O, F, Ne, Na, Al, P, S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Co, and Ni. The total content of predicted elements in SN 2018xx is larger than that in SN 2019gbx.
