Supernovae (SNe) mark the violent termination of a star’s life in an explosion. They are classified according to their light curve as type I or II, with the type I SNe producing very similar light curves, while the SNe type II are more diverse. Spectroscopic observations reveal the presence of hydrogen in SNe type II, while no hydrogen lines are detectable in SNe type I. According to their spectral appearance the type I class can be further subdivided into Ia, Ib, and Ic.
