Relative frequencies of core-collapse supernovae as a function of metallicity: observations vs theoretical predictions

Claudia P. Guti\'errez, Dimitris Souropanis, Emmanouil Zapartas, Joseph P. Anderson, Llu\'is Galbany, Luc Dessart, Rubina Kotak

SESNe-to-SNe II ratios increase slightly with metallicity, consistent with binary or rotating-star models.

Claims

C1strongest claim

For the SESNe-to-SNe II ratios, we confirm a slight increase with metallicity, reflecting a higher fraction of SESNe in metal-rich environments. Comparison with theoretical predictions shows that models including either binary interactions or rotation can broadly reproduce the observed trends, although degeneracies remain, and no single scenario uniquely explains the data.

C2weakest assumption

That global host-galaxy parameters (magnitudes, stellar masses, oxygen abundances) reliably trace the local metallicity at the supernova explosion site and that distance-limited subsamples sufficiently remove selection biases present in targeted surveys.

C3one line summary

Observations show a slight rise in stripped-envelope supernovae relative to hydrogen-rich ones at higher metallicities, with binary-interaction or rotation models able to match the trends though no unique scenario fits best.
