A spinning neutron star that appears to give off radio wave pulses is called a pulsar
Explanation:
Usually, neutron stars are detected to pulse radiowaves as well as other electromagnetic radiation, and pulses are termed as neutron stars. The radiation of pulsars is typically induced by particle acceleration close to their magnetic poles that need not be affiliated with the neutron star's axis of rotation.
Typically, neutron stars are known to emit radio waves as well as other electromagnetic radiation and neutron stars that observed with pulsed are termed as pulsar.
A pulsar, a pulsating star, is formed when a massive star reaches its end stage. At this stage, the core of the star is compressed and collapses into a Neutron star. It retains most of its angular momentum but a tiny fraction of its progenitor's radius. Beam of Electromagnetic radiations are emitted along the magnetic axis of the the Pulsar. When this beam is pointed towards the Earth, it appears like a pulsating star (just like a lighthouse is seen only when observes is in line of the beam of light) thus they are names as Pulsar.
