They rotate with an amazingly stable rotation rate.
Neutron stars rotate rapidly due to their conservation of angular momentum. When a massive star collapses into a neutron star, its core spins faster as it contracts. Since angular momentum is conserved, the neutron star continues to rotate rapidly as a remnant of the collapsed star.
Revolve means they have to have something to revolve around. Do you mean rotate? [See related question] All neutron stars rotate due to the conservation of momentum. At birth they move incredibly quickly - sometimes a thousand times a second but as they age, they will slowly slow down.
Stars actually do rotate.
The North Star, or Polaris. This star remains nearly stationary in the sky while all other stars seem to rotate around it due to the Earth's rotation on its axis.
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
Some neutron stars that emit pulses of radiation are known as pulsars. Pulsars rotate rapidly and emit beams of electromagnetic radiation from their magnetic poles, which are observed as regular pulses when they sweep across the Earth.
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
No, not all neutron stars are pulsars. Pulsars are neutron stars that emit beams of radiation that are detectable from Earth as rapid pulses of light. While many neutron stars are pulsars, not all neutron stars exhibit this pulsing behavior.
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
That would be a collission between two neutron stars. Since many stars are actually double stars, this can happen now and then.
Neutron stars range in size from 20 to 40 kilometers (12 to24 miles) in diameter.
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.
