That would be a super-nova
A Nova or a Supernova.
The giant star
After a supergiant star, the star can evolve into a supernova, which is a massive explosion that signals the end of the star's life. Depending on the mass of the star, it can then collapse into a neutron star or a black hole.
no, its a massive compression of a star under its own gravity. it then turns into an extremely dense star called a red dwarf.
A huge explosion from a dying star.
Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough. However the explosion from a Red Super Giant can be called a supernova. A normal Red giant doesn't actually explode, the core just collapses again to cause a white dwarf and the outer layers are ejected to form planetary Nebulae.
There are several different kinds. An explosion ON a star is usually called a "nova" (from the Latin for "new", because this results in the star brightening significantly, thus appearing to be a "new star"). The star itself usually survives, and the cycle will probably repeat several times. The explosion OF a very large star is called a "supernova", and again there are different kinds. Stars generally either do not survive this, or survive only in very changed form (as a neutron star or black hole).
Hypergiant.
