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 ...
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.
The Pulsars was a new wave/indie rock band from Chicago, Illinois, led by Dave Trumfio and his brother, Harry Trumfio. They signed to Herb Alpert and Jerry Moss 's Almo Sounds label and recorded two albums in the mid-1990s, [1] one of which was released and another that has yet to be released.

22. Apr. 2024 · Pulsar, any of a class of cosmic objects, the first of which were discovered through their extremely regular pulses of radio waves. Some objects are known to give off short rhythmic bursts of visible light, X-rays, and gamma radiation as well, and others are “radio-quiet” and emit only at X- or.

12. Dez. 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.
