Supernovae can't be typecast

Article Abstract:

A simple code which distinguishes the supernovae into types I and II based on their optical spectra has been developed by astronomers. Supernovae type II is formed by the gravitational collapse of the iron core formed by nuclear fusion in the center of a large star. The conditions are completely out of equilibrium but the composition remains normal. On the other hand, a type I supernovae is completely abnormal with type Ia producing iron and cobalt emission while type Ib develop helium absorption lines and subsequently, oxyygen and calcium emissions.
