[C] The binary … WebA pulsar is a spinning neutron star that seemingly emits pulses at a regular interval. These flashes are because of the magnetic field of the star sending gas to the poles, exciting the gas and emitting light in the form of radio and X-rays. Moreover, if the magnetic field is strong enough it can cause cracks in the surface of the star, sending ...

What are pulsars? Space

WebA pulsar is a rapidly rotating neutron star. The “pulses” of radiation we see from a pulsar are due to a misalignment of the neutron star’s rotation axis and its magnetic poles. Neutron stars for which we see such pulses are called “pulsars.”. A pulsar emits radio pulses at regular intervals. If the radio beam sweeps past the Earth as ...
