How many types of supernova are there?

Answer 1

Supernovas [See Link] are classified according to the absorption lines of different chemical elements that appear in their spectra. The classification can be simplified to Type I or Type II Type II - If a supernova's spectrum contains a line of hydrogen in the visual portion of the spectrum. Type I - all the rest. These are broken down even further. Type:- Ia - When a white dwarf merges with another star. Ib & Ic are formed by massive stars running out of fuel but have lost the outer layer of hydrogen and helium like Wolf-Rayet stars Type II are the "normal" types of supernova, where massive stars can no longer maintain hydrostatic equilibrium and the core collapses IIP Reaches a "plateau" in its light curve IIL Displays a "linear" decrease in its light curve Supernova [See Link] classifications are based on chemical composition.

Answer 2

In simple terms, there is only one type of supernova - A star that explodes.

It can then be sub categorised into two types I & II supernova.

These can also be sub categorised into Ia, Ib and Ic - IIP & IIL

Answer 3

There are Type:-

• 1a
• 1b
• 1c

and Type :-

• IIP
• IIL
• IIn
• IIb

Supernovae that do not fit into the normal classifications are designated peculiar, or 'pec'.

Answer 4

There are two main types of supernovae: Type I and Type II. Type I supernovae occur in binary star systems where one star has exhausted its nuclear fuel and accretes matter from its companion, triggering a violent explosion. Type II supernovae occur when a massive star reaches the end of its life and undergoes a core collapse, leading to a catastrophic explosion.
