The classification of supernovae is based mainly on the appearance of their optical spectra (Figs. 2 and 3). Type I supernovae (so named because the first well-observed events of the 1930s …

Jan 9, 2008 · A further sub-division of Type I is made according to a strong silicon line that is seen in Type Ia objects (about 24% of all supernovae [1]) at peak luminosity but is absent in Type …

Core-collapse supernovae (SNe) are defined as explosive events that occur in massive stars with initial masses greater than approximately 8–10 solar masses, typically resulting from the …
