This is because of a law called conservation of angular momentum. If a star - which will usually have some rotation, and therefore some rotational momentum - collapses to a size of 20-30 km., angular momentum is conserved. Since the diameter decreases, it must spin faster. (Angular momentum is the product of a quantity called moment of inertia, which depends on the diameter of an object, and angular velocity.)

Why does theory predict that a neutron star should spin fast?
Neutron stars are born from massive stars collapsing, which conserves the original star's angular momentum. Since the original star had a slow rotation, the neutron star that forms from it will have a faster spin due to the conservation of angular momentum.
Two important properties of young neutron stars are?
Rapid rotation: Neutron stars can spin incredibly fast, with some completing hundreds of rotations per second. Strong magnetic fields: Neutron stars have extremely powerful magnetic fields, magnitudes stronger than any other object in the universe, which can influence their behavior and emit radiation.
Why do neutron star spin so rapidly?
Neutron stars spin rapidly due to the conservation of angular momentum. When a massive star collapses into a neutron star, its rotation speed increases dramatically due to the conservation of angular momentum, just like a figure skater spinning faster when they pull their arms in. Additionally, the rapid rotation can be sustained by the incredibly high density and strong gravitational forces present in neutron stars.
What are the unusual properties of neutron stars?
Neutron stars are incredibly dense, with masses greater than the Sun packed into a sphere only about 12 miles in diameter. They have intense magnetic fields and can spin rapidly, emitting periodic pulses of radiation, hence their classification as pulsars. Neutron stars are also believed to contain the densest form of matter in the universe, composed primarily of neutrons.
Pulsars cannot be spinning white dwarfs because?
Pulsars are not spinning white dwarfs because they are neutron stars. Neutron stars are much more massive and compact than white dwarfs, resulting from the collapse of the core of a massive star. Pulsars are rapidly spinning neutron stars that emit beams of radiation from their magnetic poles.
Why is a neutron star expected to spin rapidly?
All young neutron stars spin rapidly. You might be confused with a pulsar. See related questions.

Why do pulsar stars spin?
Pulsar stars spin because they are formed from the collapsed core of a massive star that has exploded in a supernova. During the collapse, the core's rotation becomes faster due to the conservation of angular momentum. This rapid rotation causes the neutron star to spin rapidly, emitting beams of radiation that we detect as pulses from Earth.

Stars that spin rapidly and give off radio waves are called?
pulsar
What is spinning neutron star called?
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.

Neutron stars are also believed to contain the densest form of matter in the universe, composed primarily of neutrons.
Are all neutron stars pulsars?
No, not all neutron stars are pulsars. Pulsars are a type of neutron star that emits beams of radiation, which can be detected as pulses of light. Some neutron stars do not emit these beams and are not classified as pulsars.
A neutron star that rotates rapidly and emits light?
It's called a pulsar. However - ALL young neutron stars emit the said beam. It's only if that beam is detectable on Earth is it called a pulsar. So a Neutron Star and a Pulsar are the same thing. See related questions. but then again they are different.
Pulsars cannot be spinning white dwarfs because?
Pulsars are not spinning white dwarfs because they are neutron stars. Neutron stars are much more massive and compact than white dwarfs, resulting from the collapse of the core of a massive star. Pulsars are rapidly spinning neutron stars that emit beams of radiation from their magnetic poles.
Why don't all supernova remnants contain pulsars?
A "pulsar" is a rapidly-rotating neutron star, with a core of collapsed matter. The pulsar rotates because the original star rotated. If\\ WHEN a massive star becomes a supernova, the force of the explosion will crush the core of the star into either a neutron star or a black hole, if the original star was massive enough. The angular momentum (the "spin energy") of the original star doesn't disappear; like a figure skater pulling in her arms to spin faster, the neutron star will spin more rapidly because it has collapsed in size. If the neutron star's axis is pointed somewhere close to Earth, we detect the pulsating x-rays and we call it a "pulsar". So to answer the question, all supernova remnants contain either neutron stars or black holes, but they are pulsars only if they spin rapidly.
