Stellar Death of High Mass Stars
When stars go supernova
While most stars become planetary nebula at the end of their lives, stars of more than 8 solar masses when they became main-sequence stars will die in fiery explosions.
Other types of supernova
An accreting white dwarf in a close binary system can also become a supernova when carbon burning causes explosions throughout this degenerate star.
Classification of Supernova
Ia- These supernovae are produced by accreting white dwarfs in close binaries. They have spectra that have strong absorption line of ionized silicon.
Ib- These supernovae lack the ionized silicon line but have a strong helium absorption line.
Ic- These supernovae lack the ionized silicon line and do not have a strong helium absorption line.
These are created by the deaths of massive stars like Type Ib and Ic. They occur when the star has lost a substantial part of its outer layers before exploding.
