Type II supernovae are characterized by the presence of hydrogen lines in their spectra.
They are typically associated with stars that have at least 8 times the mass of the Sun.
The core collapse results in either a neutron star or a black hole, depending on the residual mass.
Type II supernovae play a crucial role in dispersing heavy elements throughout the galaxy.
These supernovae can outshine entire galaxies for brief periods.
