There are numerous classes of Type II supernova Metagenix Alpha x explosions, which are labeled in line with their ensuing mild curves. A mild curve is a graph of luminosity versus time inside the aftermath of the explosion. Type IIb supernovae like SN ig display simplest a vulnerable hydrogen line in their initial spectrum--that's the cause why they're categorised as Type II.
