Random forest models using early magnitudes, time differences, and new magnitude rates identify up to 13.6% of true broad-lined Ic supernovae in unseen test data.
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.
Rotating stellar models initialized with observed velocity distributions yield modestly lower initial mass estimates for SN II progenitors than non-rotating models, with an upper limit of 20.4 solar masses.
