Definition of pulsar in English:



  • A celestial object, thought to be a rapidly rotating neutron star, that emits regular pulses of radio waves and other electromagnetic radiation at rates of up to one thousand pulses per second.

    • ‘Black holes, the cosmic microwave background, pulsars, neutron stars, gravitational lenses, gravity waves - these are just a few of the phenomena that would make no sense without general relativity.’
    • ‘The object is being stimulated by jets from a rapidly spinning (about thirty times a second) neutron star called a pulsar.’
    • ‘These emanations come from rapidly spinning neutron stars called pulsars - rotating beacons that periodically send energy in the direction of the earth.’
    • ‘The Universe has its own heavenly sounds, such as pulsars, planetary magnetospheres and solar winds.’
    • ‘I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes.’


From puls(ating st)ar, on the pattern of quasar.
