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]

Jan 24, 2023 · Pulsars are 'cosmic lighthouses' that when seen from Earth appear to be flickering stars, but actually consist of exotic stellar remnants called neutron stars.

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. For a while, these cosmic radio sources were called LGM – …

This map shows the position of almost every radio pulsar known to modern researchers. The slider on top of the page lets you move through space, exploring different distances from …

The Hulse–Taylor pulsar (known as PSR B1913+16, PSR J1915+1606 or PSR 1913+16) is a binary star system composed of a neutron star and a pulsar which orbit around their common center of mass. It is the first binary pulsar ever discovered.

Jul 13, 2024 · Using the 64m Parkes radio telescope (Murriyang), astronomers have made new mass and distance measurements of the closest and brightest millisecond pulsar to Earth, PSR J0437-4715 at radio frequencies.

A good example showing how pulsar timing can be extremely useful is timing-based pulsar astrometry. Pulsar positions on the sky are determined by timing a pulsar over the course of a year as the Earth orbits the Sun and tracking the changing Roemer delay.

Jul 15, 2022 · 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.

Mar 5, 2010 · A pulsar is a neutron star which emits beams of radiation that sweep through the earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The "pulses" of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's rotation axis and its magnetic axis.

May 24, 2019 · The first known pulsars, for example "Little Green Man" or PSR B1919+21, were radio pulsars; your graph shows those waves are detectable from Earth's surface. I stumbled upon this article which lists the frequency of some of the pulsars:
