The periods of pulsars make them very useful tools for astronomers. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered in 1992 around a pulsar, specifically PSR B1257+12.
24 de ene. de 2023 · Pulsars are rapidly rotating neutron stars that blast out pulses of radiation at regular intervals ranging from seconds to milliseconds. Pulsars have strong magnetic fields that funnel...
22 de abr. de 2024 · 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 pulsars have a mass 1.35 times that of the Sun.
12 de dic. de 2019 · Pulsars, which are one class of neutron star, spin up to hundreds of times each second and sweep beams of energy toward us with every rotation. J0030 revolves 205 times per second. For decades, scientists have been trying to figure out exactly how pulsars work.
1 de dic. de 2017 · True to their name, pulsars are primarily pulsating radio sources. We know of some 2,500 radio-emitting pulsars and believe there may be up to 100,000 in our galaxy. Only about 20 have been...
3 de nov. de 2011 · The fastest of these so-called millisecond pulsars whirls at 43,000 revolutions per minute. This plot shows the positions of nine new pulsars (magenta) discovered by Fermi and of an unusual millisecond pulsar (green) that Fermi data reveal to be the youngest such object known.
1 de ago. de 2017 · Article. 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.
