When a stellar remnant is over about 3 to 4 times the mass of the sun (see Tolman-Oppenheimer-Volkoff limit) it is estimated to have insufficient outward pressure to resist gravitational collapse into a black hole. Note that larger stars would often explode into a supernova or become a planetary nebula, losing most of their mass this way first - perhaps over 75 percent - and thus the original star's mass needed to have a remnant heavy enough to collapse in a black hole would be much heavier than 3 times solar mass.
A neutron star or a pulsar, or a black hole.
No. A black hole may be the remnant of the core of what was once a blue star, but the black hole itself is as black as anything can possibly be.
Either a black hole, or a neutron star. That depends on how much mass is left after the supernova explosion.
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.
When it turns into a black dwarf neutron star or black hole.
A black hole originated as a star, that is, the star converted to a black hole.
A neutron star or a pulsar, or a black hole.
A black hole does not create a star. A black hole is formed when a star dies.
The core of the star can collapse to form a neutron star or a black hole. The outer layers of the star can be ejected into space, enriching the surrounding interstellar medium with heavy elements.
Yes. A black hole is a collapsed star.
That refers to a black hole - but a black hole is not exactly a star.
Yes black hole is last stage of a star
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
No. A black hole may be the remnant of the core of what was once a blue star, but the black hole itself is as black as anything can possibly be.
A supernova, resulting in either a neutron star or black hole. Also may heavy elements are blown out of the star during the explosion.
A black hole is a collapsed star with such a strong gravitational pull that not even light can escape from it. This phenomenon occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. The boundary surrounding a black hole, beyond which nothing can escape, is called the event horizon.
Either a black hole, or a neutron star. That depends on how much mass is left after the supernova explosion.
