In 2016, a white dwarf in the binary system AR Scorpii was identified as a pulsar (it is often mistakenly called the first discovered pulsar-like white dwarf). The system displays strong pulsations from ultraviolet to radio wavelengths, powered by the spin-down of the strongly magnetized white dwarf.
Jan 24, 2023 · The periodicity of pulsars is caused by these beams of light crossing the line of sight here on Earth, with the pulsar appearing to 'switch off' at points when the light is...
Jul 15, 2022 · A pulsar is a rapidly spinning neutron star. So, what’s a neutron star? A neutron star is the small, incredibly dense remnant of a much more massive star. Neutron stars are so dense that if...
May 24, 2022 · Bibliography. 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...
Nov 21, 2013 · Known as pulsars, these stellar relics get their name because of the way their emissions appear to be “pulsating” out into space. Not only are these ancient stellar objects very fascinating...
Jul 12, 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.
We continue with a section on the theory of pulsars where we explain why pulsars are thought to be neutron stars (the collapsed core of a star that underwent a supernova explosion). We explain how these pulsars are actually studied today and what we can learn from these amazing objects.
Jun 14, 2007 · A pulsar is a rapidly rotating neutron star. A neutron star is one of the end points of the life of a massive star, after it explodes in a supernova explosion. A neutron star which retains a strong magnetic field produces pulses of radiation along that field.
Pulsars channel electromagnetic radiation into bright, laser-like beams from both their north and south poles thanks to magnetic fields that are as much as a quadrillion times stronger than Earth's. It's not clear where this light comes from, with several sources possibly responsible for the spectrum of light.
