Nobody knows for sure, but billions of years. It would also depend on when the neutron star, no longer becomes a star. Is it when it stops radiating heat, or x-rays? The star or the remains will continue to be a physical property but will no longer radiate any energy.
Depending on the mass of the original star, it is either a black hole or a neutron star.
They are all astronomical terms for stars or star related.
A pulsar is a type of neutron star, a collapsed core of an extremely massive star that exploded in a supernova. Whereas white dwarfs have incredibly high densities by earthly standards, neutron stars are even denser, cramming roughly 1.3 solar masses into a city-sized sphere.
Dangerous. Novas, or supernovas. Tycho Brahe coined the phrase "nova stellarum" when a "new star" appeared in the night sky. We now know that he was observing a supernova, the death throes of a very massive star.
The neutron star so affected wouldn't really notice. The mass of the neutron star is huge compared to that of the material in the accretion disk. And that matter, when it falls in, wouldn't really "slow" the spin of the star much unless there was a gigantic quantity of matter falling in and/or it acted over a very long period.
A supernova is when a massive star explodes. A neutron star is what can be formed after a supernova explosion. See related questions
No. A neutron star is left behind after a supernova. However, some gamma ray bursts may result from a collision between neutron stars.
The supernova remnant will either be a neutron star or a black hole.
Yes, the first neutron star was observed in a supernova remnant. The object, named PSR B1919+21, was discovered in 1967 in the Crab Nebula, the remnant of a supernova that exploded in the year 1054 AD.
A neutron star
neutron star has been observed at the center of a supernova remnant, known as the Crab Nebula. This neutron star, also called a pulsar, spins rapidly, emitting beams of radiation that are observed as pulses by astronomers.
Neutron Star
A supernova happens when most of the core of the collapsing star has become neutrons, held up against gravity by neutron degeneracy pressure. At this point a shockwave reflects from the neutron star surface, driving the supernova explosion.So the answer to your question is neutrons.
