That's because of conservation of angular momentum - and the fact that neutron stars are very small. If a star the size of our Sun rotates (for example) once a month, once it shrinks to a diameter of 20-30 km., it will have to rotate several times per second in order to conserve angular momentum.
What else can I help you with?
What are remnants of high mass star?
Neutron stars and black holes.
What evidence can you cite that pulsars are neutron stars?
A pulsar is a neutron star that rotates and sends a beam of electromagnetic radiation. This is known because only a very dense source of such radiation would be capable of rotating that quickly without disintegrating.
Why do neutron star spin so rapidly?
Most stars spin (albeit is very slowly), but when the star starts to shrink it will speed up due to conservation of angular momentum. Moreover because a neutron star is so very heavy it takes a long time for it to slow down (breaking can occur via magnetic fields for example). You can test this principle yourself by sitting into an office chair, spreading your arms, and have someone give you a good whirl. You will find that while spinning you will spin faster if you pull your arms inwards and slower if you put them out again.
Pulsars cannot be spinning white dwarfs because?
because of the great mass of the star, the gravity of it is very high. So after its death, it actually contracts so tightly that even protons and electrons combine to form neutron and thus results to a star called neutron star. If its previous mass is considerably low, then it could have become a white dwarf
When A neutron star is the densest substance in the universe What does it tell you about its mass and volume?
It means it's mass is very high and its volume is very low. A standard neutron star has a mass thousands of times greater than the sun, but a volume of a small city. This ridiculously high density and pressure also account for the high temperatures of neutron stars. PS. Quark stars are denser than neutron.
What are remnants of high mass star?
Neutron stars and black holes.
What is the remains of of high mass stars?
It can be a black hole or a Neutron Star
What causes pulsating variable stars to pulsate?
When the core of a massive star is compressed during a supernova explosion, then collapses into a neutron star, it retains most of its angular momentum.Since it has only a tiny fraction of its original radius, a neutron star is formed with a very high rotational speed.A pulsar is a highly magnetised, dense neutron star emitting a beam of electromagnetic radiation.

How do pulsars accelerate to dizzying rotational speeds?
When a neutron star is first formed (Pulsars are just neutron stars - see related question) it retains most of its angular momentum. As it now only has a tiny fraction of its "parent's" radius, a neutron star is formed with a very high rotation speed. It's similar to watching ice skaters spinning with their arms out and then suddenly bringing them to their sides.
What are the small dense remains of a high-mass star called?
The small dense remains of a high-mass star are called neutron stars or black holes, depending on the mass of the star. Neutron stars are formed when the core collapses under its own gravity, while black holes are formed when the core collapses into a singularity.
What are the densest stars?
The densest stars are neutron stars, which are formed from the collapsed core of a massive star after a supernova explosion. Neutron stars are incredibly dense, with a mass greater than that of the Sun but compressed into a sphere only about 10 kilometers in diameter. The density of neutron stars is so high that a sugar-cube-sized amount of neutron star material would weigh as much as Mount Everest.
Where do neutron stars form?
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.
What is made when stars die?
There are three types of stellar remnants. Low to medium mass stars will become white dwarfs. High mass stars will become neutron stars. Very high mass stars will become black holes.
Can Neutron stars turn back into a normal star and if so how?
No. The mass of a neutron star is so compact and the gravity so high that it could never again become a regular star. Besides, neutron stars come from the cores of stars that have already gone nova. All the hydrogen was already fused into heavier elements.
Why are neutron stars made out of different matter than earth?
Neutron stars are made of the same matter as Earth, but they have so much mass that their matter has a high density and the atoms have been crushed with everything compressed into neutrons.
