Type Ic core-collapse supernovae explode in systematically younger environments than Types II, IIb, and Ib, indicating they arise from more massive progenitors via a distinct channel.
Direct inclusion of CMFGEN atmosphere grids in STAREVOL evolution calculations lowers effective temperature and radius in the Wolf-Rayet phase to better match observations while leaving internal structure and chemical evolution unchanged.
Late-time radio observations of Type IIn and II-L supernovae show a range of CSM densities and mass-loss rates, with detections supporting a continuum between subtypes driven by recent dense material rather than long-term mass loss.
