Weird white dwarf pulsar baffles boffins as its pulsating pattern changes over decades

Scientists trying to crack the mystery behind the fastest-pulsating white dwarf have found that its brightness levels change over a timescale of decades. AR Scorpii is a distant, peculiar binary star system located 380 light years away. It’s made of a collapsed white dwarf star circling its larger red dwarf companion. It was …

Pulsating white dwarf described as a 'dynamo' found, no, not in the back pages, 380 LY away

Fifty years after pulsars were discovered, scientists in the UK and South Africa have spotted the first white dwarf that mimics the emissions of a neutron star. Collapsed star AR Scorpii (AR Sco), spotted 380 light years away by a team from the University of Warwick and the South African Astronomical Observatory, is about the …

Einstein@home's 13 new pulsars

Home Einsteins help turn up 13 new pulsars

The Einstein@home project has announced the discovery of 13 neutron stars in its distributed analysis of gamma ray data from the orbiting Fermi telescope. The bunch of “young” pulsars are believed to have formed between tens and hundreds of thousands of years ago, and among them are three particular curiosities: two that are …

NASA eyes up supermassive black holes, neutron stars

NASA will embark on a new mission to explore supermassive black holes, neutron stars, and pulsars hidden within the depths of space. The Imaging X-ray Polarimetry Explorer (IXPE) mission was chosen among 14 other proposals during the rigorous selection process for NASA's Astrophysics Explorer programmes. It's expected to …

Astroboffins find first 'wind nebula' around rare 'magnetar' star

Astronomers have found a “wind nebula” around a rare ultra-magnetic neutron star for the first time. Neutron stars are commonly found as pulsars – incredibly energetic fast spinning neutron stars which release radio, visible light, X-rays and gamma rays. They have strong magnetic fields that are 100 billion to 10 trillion …

SPLAT! STAR THWACKED, GUTS flung into space at 15 per cent of LIGHTSPEED

In perhaps the most violent punch that has ever been witnessed by humanity, a speeding pulsar has smashed right through a disk of matter bulging from the middle of a hefty star and blown a massive chunk of it guts into interstellar space at a significant fraction of light speed. That's according to top space boffins peering …

High school students' record-setting pulsar STUMPS BOFFINS

A bunch of high-school students has turned up a record-setter in the world of astro-boffinry: a pulsar with the biggest-ever orbit around a neutron star. That's exciting to astrophysicists, because the orbital oddity creates a new set of boundaries for such objects – and thus, a new line of investigation to help understand …

Second galactic flip-flop pulsar surprises boffins

Video “Where did it go?” is the kind of question astrophysicists love to answer, and work by NASA's Fermi gamma-ray space telescope has helped find out what happened to a radio pulsar that seemed to go dark in 2013. The mystery arose in June 2013: a pulsar's radio beacon vanished to be replaced by a huge increase in its gamma ray …

Two white dwarfs and superdense star. Yup, IDEAL for gravity lab in the sky - boffins

Boffins have discovered a unique triple star system that could help them to probe one of the most fundamental physics problems of all: the true nature of gravity itself. Millisecond pulsar, left foreground, is orbited by a hot white dwarf star, centre, both of which are orbited by another, more-distant and cooler white dwarf, …

Boffins baffled over pulsar with 'split personality'

A pulsar that randomly and without warning dramatically changes its pattern of radio wave and X-ray emissions has surprised a team of astronomers, who wrote that it "challenges all proposed pulsar emission theories". A pulsar with glowing cones of radiation Pulsars are spinning neutron stars the size of a small city, with a …

NASA's ageing black hole-stalking probe switched off

Astronomers are marking the decommissioning of a satellite that has spent 16 years peering into black holes and neutron stars. NASA's Rossi X-ray Timing Explorer (RXTE) helped astronomers establish the existence of highly magnetised neutron stars and collected the first evidence of the spacetime-distorting frame-dragging …

Seagate extends enterprise disk and SSD lines

Seagate has extended its enterprise disk and solid state storage products in a comprehensive announcement following hard on the heels of Western Digital buying Hitachi GST. Second generation Pulsar solid state drives (SSD) have been announced with a 2-bit, multi-level cell Pulsar.2 and a higher-performance single level cell …

Mobile companies unite on Apple - Google threat

When it comes to easing the pain of building applications for developers that target different mobile devices, many have come with supposed remedies and many have either disappeared or helped make things worse. Now it's the turn of Eclipse, more famous for its work on servers and desktops - only the open-source foundation …

Ancient pulsar still radiating like a young 'un

NASA's Chandra X-ray Observatory has detected what the agency describes as a "surprisingly active" ancient pulsar - the oldest such body ever spied in the X-ray band and still radiating after around 200m years. PSR J0108-1431, aka J0108 for those in a hurry, lies at around 770 light-years from Earth. It's an "isolated" pulsar …

NASA spots 'gamma ray-only' pulsar

NASA's Fermi Gamma-ray Space Telescope (formerly known as GLAST) has spied the first "gamma ray-only" pulsar - a 10,000 year-old stellar remnant which uniquely doesn't appear to emit pulses at either radio, visible light or X-ray wavelengths in common with the 1,800 or so similar objects catalogued to date. An artist's …
