Radio star

Stellar radio sources, radio source stars or radio stars are stellar objects that produce copious emissions of various radio frequencies, whether constant or pulsed. Radio emissions from stars can be produced in many varied ways.

Pulsars, a type of neutron star, are examples of radio stars. Rotation-powered pulsars are, as the name suggests, powered by the slow-down of their rotation. The rotation powers a magnetic field, which generates the radio emissions. Not all rotation-powered pulsars generate their pulses in the radio spectrum. Some of them, from the millisecond pulsars, generate X-rays instead. Aside from radio pulsars and X-ray pulsars, there are also gamma ray pulsars, which are mostly magnetars. Some radio pulsars are also optical pulsars.
