How big must a star be to form a black hole
Web18 de jun. de 2024 · A black hole of a given mass will probably have arisen from the collapse/supernova of a much more massive star. In particular, stars with an initial mass of less than around 15-20 solar masses are unlikely to leave a black hole remnant at all. Stars of $<8$ solar masses end their lives as white dwarfs and those with $8$ to $\sim 15$ … Web$\begingroup$ @Jus12: there is no event horizon anywhere in ordinary matter. Once an event horizon forms, all of the matter inside must collapse to a black hole. This is the key difference between a neutron star and a black hole--a neutron star is made up of (very dense) ordinary matter in a stable configuration.
