Because of the conservation of rotational momentum. As a stars core collapses, it retains the original rotational velocity. As a pulsar or neutron star's original size was in the region of 60,000 time greater that it's current form, the rotational speed is multiplied by this factor.

Maintaining the rotational momentum requires the star to spin faster.

How fast can a Chinese yoyo spin?

It can spin pretty fast. On impact, it can break a lot of things, including the yoyo.


What makes a pulsar pulsate?

A neutron star is unimaginably dense. It contains the mass of the Sun, but has that mass squeezed into a ball perhaps 20km (12 1/2 miles) across. Further, neutron stars are so small that they can spin very rapidly, many times per second or faster. When they spin they emit electromagnetic radiation which can appear as flashes from earth. If the magnetic pole of the neutron star is "pointed" [See related link - Pictorial of pulsar] towards Earth, they are called pulsars, as they "pulse" as they spin and can be detected. The flashes produced by the pulsars are detected as the electro magnetic radio waves caught up by the radio telescopes


What is the favored explanation for the rapid spin rate of millisecond pulsar?

The favored explanation for the rapid spin rate of millisecond pulsars is that they are formed through the process of accretion from a binary companion. As material falls onto the pulsar from the companion star, its rotation speed increases due to conservation of angular momentum. This process can ultimately accelerate the pulsar to millisecond spin periods.


Why do pulsars have large magnetic fields?

Pulsars are formed from the cores of massive stars that have exploded in supernovae. During the collapse, their magnetic fields get amplified to extremely high levels due to conservation of magnetic flux. This results in pulsars having large magnetic fields.


Why aren't all neutron stars seen as pulsars?

Not all neutron stars are seen as pulsars because pulsars emit beams of radiation that are only visible if they are pointed towards Earth. If a neutron star's beams are not aligned with our line of sight, it will not appear as a pulsar.

Why do pulsars spin so fast?

Because of the conservation of rotational momentum. As a stars core collapses, it retains the original rotational velocity. As a pulsar or neutron star's original size was in the region of 60,000 time greater that it's current form, the rotational speed is multiplied by this factor.

Millisecond pulsars that are very old are?

believed to be the result of mass transfer from a companion that increases the spin of the pulsar.


Why can Sonic spin?

Sonic can spin because he runs so fast it looks like he is spinning.


Where are pulsars located in space?

Pulsars are located every where around the universe keep in mind pulsars are neutron stars so that means they were formed by large stars that have aged and died out

How are pulsars related to supernovas?

Pulsars are formed during a supernova event when a massive star explodes, leaving behind a dense core called a neutron star. As this neutron star rotates rapidly, it emits beams of radiation that we detect as pulses, hence the name "pulsars." So, pulsars are directly related to the remnants of supernova explosions.


Does the earth turn fast?

Faster than some, not as fast as others. We're used to it, and we'd probably be upset if it changed. The Earth spins at 15 degrees per hour, 360 degrees per day. Venus and Mercury hardly spin at all; 243 days for Venus, 58 days for Mercury. The Sun spins at about 27 days per rotation, but because the Sun isn't solid, different parts spin at different speeds. Jupiter takes 10 HOURS, Saturn 11 HOURS. Uranus and Neptune are faster than Earth, not so fast as Jupiter. Some pulsars - rotating neutron stars - spin tens or hundreds of times per SECOND.
