Neutron Star: An extremely compact star produced by the collapse of the core of a massive star in the supernova process.
Blackholes: If the core of a collapsing star has a mass that is greater than three Suns, no known force can prevent it from forming a black hole.
Type Ia Supernova: An explosion produced when a white dwarf becomes unstable due to the accretion of too much material or merger with another white dwarf.
Type II Supernova: A supernova that occurs when a massive star has used up its nuclear fuel and its core collapses to form either a neutron star or a black hole, triggering an explosion.
Pair-instability Supernova: A rare type of explosion predicted to occur as a consequence of the extremely high temperatures in the interiors of stars having masses of about 200 suns.
Supershells: The combined activity of many stellar winds and supernovas create expanding supershells that can trigger the collapse of clouds of dust and gas to form new generations of stars.
End phases: A star’s ultimate fate depends on its mass. It can fade into obscurity (brown dwarf or red dwarf), become a white dwarf (sun-like stars), explode as a supernova and leave behind a neutron star or a black hole (massive to very massive stars), or be disrupted entirely (white dwarfs in close binary systems, or extremely massive stars).
