Any of several celestial radio sources emitting short intense bursts of radio waves, x-rays, or visible electromagnetic radiation at regular intervals, generally believed to be rotating neutron stars.

[From pulse, by analogy with quasar.]

pulsar [ˈpʌlˌsɑː]

n

(Astronomy) any of a number of very small extremely dense objects first observed in 1967, which rotate very rapidly and emit very regular pulses of polarized radiation, esp radio waves. They are thought to be neutron stars formed following supernova explosions

[from puls(ating st)ar, on the model of quasar]

pulsar  (plsär)

A rapidly spinning neutron star that emits radiation, usually radio waves, in narrow beams focused by the star's powerful magnetic field and streaming outward from its magnetic poles. Because the pulsar's magnetic poles do not align with the poles of its rotational axis, the beams of radiation sweep around like the beacon of a lighthouse and are thus observed on Earth as short, regular pulses, with periods anywhere between 1 millisecond and 4 seconds.
