Pulsar - Wikipedia
A pulsar (from puls (ating st)ar, on the model of quasar) [1] is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. [2] .

2024年11月28日 · pulsar, any of a class of cosmic objects, the first of which were discovered through their extremely regular pulses of radio waves. Some objects are known to give off short rhythmic bursts of visible light, X-rays, and gamma radiation as well, and others are “radio-quiet” and emit only at X- or gamma-ray wavelengths.

2022年5月24日 · A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar …
What’s a pulsar? Why does it pulse? - EarthSky
2022年7月15日 · Bottom line: A pulsar is a neutron star with its poles aimed toward Earth so that we can see pulses of light resulting from the star’s strong emission when it’s rapidly spinning.
Pulsars | Facts, Sound, Discovery, Information, History & Definition
2020年8月17日 · A Pulsar is a core of a star that has collapsed into a neutron star. Pulsars spin very rapidly and have strong magnetic fields. A Pulsars powerful magnetic field produces a thin yet strong beam of electromagnetic radiation that is shot into space.
Introduction to Pulsars - NASA
2007年6月14日 · A pulsar is a rapidly rotating neutron star. A neutron star is one of the end points of the life of a massive star, after it explodes in a supernova explosion. A neutron star which retains a strong magnetic field produces pulses of radiation along that field.
Pulsars Astronomy – National Radio Astronomy Observatory
From the Earth, a pulsar looks like a star that has a pulse, a rapid beat picked up only by radio telescopes. Discoverers Jocelyn Bell and Antony Hewish noticed that these beats were so regular that they seemed manmade.
What Is a Pulsar? | History, Types & Fascinating Traits
It’s a type of rotating neutron star, which is incredibly dense and formed from the remnants of a massive star’s explosion. As the pulsar spins, it emits beams of radiation from its magnetic poles. These beams sweep across space like a beacon, and when they point toward Earth, we detect them as regular pulses of light.
