noun a celestial object, thought to be a rapidly rotating neutron star, that emits regular pulses of radio waves and other electromagnetic radiation
adjective pulsar (used to describe something related to or characteristic of pulsars)
Pulsars are highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation out of their magnetic poles.
Pulsars are used as natural laboratories for testing theories of gravitation, the nature of matter at extremely high densities, and the behavior of matter and radiation in super-strong magnetic fields.
Pulsars are studied by astronomers to better understand the nature of these rapidly rotating neutron stars.
Physicists use pulsars to test theories of gravity and general relativity.
Engineers may use pulsar data for navigation systems and timing applications.
Astrophysicists study pulsars to gain insights into the behavior of matter under extreme conditions.
