A supernova resulting in either a neutron star, or a black hole.
A Nova or a Supernova.
After a high mass star explodes, the leftover material forms a remnant called a neutron star or a black hole. If the core of the star is less than about 3 times the mass of the Sun, it collapses to form a neutron star. If the core is more massive, it collapses further, causing the gravitational collapse to form a black hole.
When a single high mass star explodes, it undergoes a supernova event. The core collapses inwards and then rebounds explosively, sending out a shockwave that ejects the outer layers of the star into space. This explosion can outshine an entire galaxy for a short period of time.
A neutron star is what is left behind from some supernovas, which occur when a massive star explodes.
Supernovae are massive explosions that occur when a star uses up its gas and explodes so they will only occur once a star has died.
High mass.
False. A brown dwarf is a failed star that cannot sustain nuclear fusion. When a star explodes it will leav behind either a neutron star or a black hole depending on its mass.
Roughly the same as the original star. When a star explodes nearly all of it's mass is ejected into space.
The life of a high mass star goes like this: A nebula gets hot and nuclear fusion binds it into a high-mass protostar the protostar ages into high-mass, very hot star that hot star explodes into a supergiant, which proceeds to explode into a supernova the supernova then shrinks into a neutron star or a black hole the life of a low- or medium-mass star goes like this: a nebula gets hot and nuclear fusion binds it into a low-mass protostar the protostar ages into a low- or medium- mass,cool star the star explodes into a red giant, the red giant explodes into a planetary nebula the nebula shrinks into a white dwarf, which then dims into a black dwarf i hope i was able to answer your question.
They are both formed when a massive star explodes as a supernova. Which, is produced depends on the original mass of the star.
A high mass star will leave behind either a neutron star of a black hole.
High mass.
