No, they cannot.
A neutron star forms when the core of a supernova is halted by rising neutron pressure (due to the increase in the density of the core). If this central core ends up having a mass greater than three solar masses, it will end up forming a black hole instead of a neutron star. A pulsar is a type of neutron star that rotates and is highly magnetized.
As such, since they are not massive enough to form a black hole in the first place, they probably won't ever become one. The only way that they could possibly become a black hole after formation is if they collide with another neutron star or black hole.
A neutron star or a pulsar, or a black hole.
A pulsar will not become a black hole because they do not implode and that is one of the key features of a star becoming a black hole. a pulsar is highly magnetized and gives off a beam of electromagnetic radiation, when viewed from a distance it will look as though it is flashing.
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
There's no mass range that's between "collapses into a neutron star or pulsar" and "collapses into a black hole". It'll be one or the other.
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.
After a supernova explosion in Betelgeuse it will definitely become at least a neutron star. However, because of it's mass it's more than likely to become a black hole. If it does, then it will be the closest black hole to Earth.
It can either become a neutron star or a black hole. If the star is between 8 and 15 solar masses, it will become an incredibly dense neutron star. If it is more than 15 solar masses, it will collapse and become an even denser black hole.
According to current theories of stellar evolution, because of the Sun's mass and chemistry most likely it will become a white dwarf. It simply lacks the weight to become a neutron star or black hole.
The long-term fate of the sun according to current theories in stellar evolution, is to become a white dwarf. It lacks the mass to further collapse into a neutron star or black hole.
If enough mass is left over after the supernova explosion, i.e. after material is blown off into space, the star will become a black hole. Less massive stars will become neutron stars. A neutron star can convert to a black hole later, if enough matter falls into it.
Neither. Our Sun will turn into a red giant, and then cool to become a white dwarf.
It depends upon the size of the star. Stars like the sun, when they collapse, become white dwarfs which are made up of pure carbon (you can call it a diamond in space). Stars a lot bigger and heavier than the sun, collapse and become a neutron star, or a pulsar (rotating neutron star), or a black hole.
