Feb 6, 2017 · An exotic binary star system 380 light-years away has been identified as an elusive white dwarf pulsar – the first of its kind ever to be discovered in the universe – thanks to research by the University of Warwick.

Jun 23, 2023 · In 2016, our conception of white dwarf stars was turned on its head with the discovery of AR Scorpii, the first confirmed white dwarf pulsar. AR Scorpii (or, AR Sco for short) was found to emit regular pulsations every 1.97 minutes, which spanned the majority of the electromagnetic spectrum.

AR Scorpii (AR Sco) is a binary pulsar that consists of a white dwarf and a red dwarf. [3] It is located close to the ecliptic plane in the constellation Scorpius . Parallax measurements made by Gaia put the system at a distance of about 380 light-years (120 parsecs).

Jun 20, 2023 · Located around 773 light-years from our solar system, this white dwarf pulsar has a mass approximately that of the sun crammed into a width around that of Earth. It is spinning around 300 times...

Jun 15, 2023 · These rapidly rotating and strongly magnetic (about a billion times the Earth’s magnetic field) white dwarf pulsars lash their stellar companion – a red dwarf – with powerful beams of charged particles and radiation, causing the entire system to brighten and fade dramatically over the minutes-long rotation period of the white dwarf.

Jun 21, 2023 · Dubbed J191213.72-441045.1, or J1912-4410 for short, the white dwarf pulsar spins 300 times faster than Earth, or about once every five minutes. And despite being a similar size to our home...

Jun 15, 2023 · White dwarf pulsars include a rapidly spinning, burnt-out stellar remnant called a white dwarf, which lashes its neighbor—a red dwarf —with powerful beams of electrical particles and radiation,...

Feb 7, 2017 · They found that the binary system AR Scorpii (AR Sco), which sits 380 light-years away in the constellation of Scorpius, contains a white dwarf acting as a pulsar. Shortly after the...

Feb 28, 2025 · Researchers have discovered the most richly pulsating ultra-massive white dwarf to date — a crystallized stellar remnant that vibrates with 19 distinct modes. This discovery paves the way for future studies of the white dwarf’s interior structure and composition.

Feb 9, 2017 · Scientists have finally laid eyes on the first white dwarf pulsar in the known Universe, and while the star is roughly the size of Earth, it's got 200,000 times more mass, and an electromagnetic field 100 million times more powerful.
