What remnant typically remains after a Core Collapse supernova involving a star 8x the Sun's mass?

Answer

Neutron star or black hole

The core collapse scenario is reserved for stars significantly larger than the Sun, specifically those at least eight times its mass. When the iron core forms, fusion ceases, gravity overwhelms the outward pressure, and the core implodes violently. This implosion generates a massive shockwave. The resulting ultra-dense remnant left behind depends on the star's initial size; it will either stabilize as a neutron star, which is a ball of neutrons only a few kilometers across compacted from an Earth-sized core, or if the original star was exceptionally massive, it collapses entirely into a black hole. The white dwarf results from lower-mass star exhaustion, and a kilonova results from a neutron star merger, not the collapse of a single massive star.
