Kiirelt pöörlev neutrontäht, mille vaadeldava kiirgus intensiivsus pulseerib väga korrapäraselt
rapidly spinning neutron star whose magnetic field produces conal beam of electromagnetic radiation that sweeps past the Earth with each rotation of the star
The precise periods of pulsars make them very useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time.
