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.

An example of this is the newly detected white dwarf pulsar, J191213.72–441045.1 (J1912–4410), the second system of its type to be found after the discovery of AR Scorpii (AR Sco) in 2016.

The future of yellow dwarf stars, like our sun, is determined almost entirely by their mass. The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae ...

At least one white dwarf, known as AE Aquarii, emits pulses of high-energy (hard) X-rays as it whirls around on its axis. "We’re seeing behavior like the pulsar in the Crab Nebula, but we’re ...

Published today in Nature Astronomy, scientists funded by the UK Science and Technology Facilities Council (STFC) describe the newly detected white dwarf pulsar, J191213.72-441045.1 (J1912-4410 ...

The pair consists of a red dwarf, and in proximity, a white dwarf pulsar the size of the Earth but 200,000 times denser, lashing its neighbour with electrical energy and particles.

The newly found white dwarf pulsar lies 773 light-years from Earth, and is spinning at a rate 300 times faster than our home planet. The white dwarf is similar in size to Earth, but has a mass ...

Astronomers have discovered a second example of a white dwarf pulsar, a rapidly spinning stellar remnant that could teach scientists more about stellar evolution.

Finding a "teenage" white dwarf pulsar is particularly exciting because this phase of a star's life is so brief, Rodriguez explains. How brief? "About 40 million years," he says.
