Ein Pulsar (Kunstwort aus engl. pulsating source of radio emission, „pulsierende Radioquelle“) ist ein schnell rotierender, stark magnetisierter Neutronenstern. Sie bestehen zu annähernd 90 % aus Neutronen, besitzen eine Masse, die etwa dem Eineinhalbfachen der Sonnenmasse entspricht aber komprimiert auf einen Radius von nur ca. 10 km ...
24. Jan. 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.
A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles.
Vor 4 Tagen · 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.

24. Mai 2022 · 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 spins. When those...
12. Dez. 2019 · Astrophysicists are redrawing the textbook image of pulsars, the dense, whirling remains of exploded stars, thanks to NASA’s Neutron star Interior Composition Explorer (NICER), an X-ray telescope aboard the International Space Station. Using NICER data, scientists have obtained the first precise and dependable measurements of both ...
