A pulsar (pulsating star, 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.

Feb 5, 2025 · Pulsars are rapidly spinning neutron stars, extremely dense stars composed almost entirely of neutrons and having a diameter of only 20 km (12 miles) or less. Pulsar masses range between 1.18 and 1.97 times that of the Sun, but most …

Jul 15, 2022 · There’s a rapidly spinning neutron star at the center of the nebula, known as a pulsar.

May 24, 2022 · Pulsars are the ultradense cores of gigantic stars that emit beams of radio waves in regular pulses, like cosmic lighthouses.

Aug 1, 2017 · A little bit of “scruff” in scientific data 50 years ago led to the discovery of pulsars – rapidly spinning dense stellar corpses that appear to pulse at Earth. Astronomer Jocelyn Bell made the chance discovery using a vast radio telescope in Cambridge, England.

Aug 17, 2020 · Currently, there are three distinct classes of Pulsars: Rotation-powered pulsars, Accretion-powered pulsars, and magnetars. Millisecond pulsars or MSP, refer to pulsars that have rotational periods in the range of about 1 to 10 milliseconds. Pulsars were first …

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 – …

Pulsars are magnetized neutron stars that appear to emit periodic short pulses of radio radiation with periods between 1.4 ms and 8.5 s.

Sep 23, 2024 · Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds. Pulsars have very strong magnetic fields , which funnel jets of particles out along the two magnetic poles.
