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] .
2023年1月24日 · Pulsars are 'cosmic lighthouses' that when seen from Earth appear to be flickering stars, but actually consist of exotic stellar remnants called neutron stars.
2025年1月11日 · 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 …
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.
2013年1月7日 · The star of this movie is the Vela pulsar, a neutron star that was formed when a massive star collapsed. The Vela pulsar is about 1,000 light years from Earth, spans about 12 miles in diameter, and makes over 11 complete rotations …
Artist’s depiction of a pulsar with the central, spinning neutron star and its powerful magnetic field (blue). Coming out of the poles are jets of charged particles escaping the star (yellow). As the star spins, the beam swings past, and we detect a pulse of radio waves.
