Gravitational waves shed light on maximum neutron star mass

22 March 2021 Astronomy Now

What is the maximum mass for a neutron star, the point beyond which a black hole forms? Gravity waves may hold clues.

Einstein@Home helps researchers confirm ‘black widow’ pulsar in binary system

5 February 2021 Astronomy Now

Astronomers confirm a rapidly spinning pulsar in an unusual binary system using a network of home computers in a citizen science initiative.

Milky Way magnetar likely source of fast radio burst

6 November 2020 Astronomy Now

Astronomers have detected the first fast radio burst ever seen in the Milky Way and say it likely was generated by a magnetar.

Gravity waves herald merger of black hole and enigmatic companion

24 June 2020 Astronomy Now

Gravity waves indicate the merger of a massive black hole and a much less massive companion that may represent a new class of objects.

Astronomers find baby pulsar – a rare magnetar – born just 240 years ago

17 June 2020 Astronomy Now

The youngest known pulsar, born in a supernova blast just 240 years ago, also is a powerful magnetar, shedding new light on an enigmatic class of stellar powerhouses.

NICER spots thermonuclear flash from pulsar detonation

8 November 2019 Astronomy Now

The NICER X-ray telescope array aboard the International Space Station has witnessed a brilliant Type 1 X-ray burst from a pulsar 11,000 light years away.

Hubble sees unusual features around ‘magnificent seven’ neutron star

19 September 2018 Astronomy Now

Beams from rotating neutron stars – pulsars – are normally seen in X-rays, gamma rays and radio waves. The Hubble Space Telescope has now seen unusual infrared emissions, possibly from “pulsar winds” or surrounding dust.

NASA hails now-departed Rossi X-ray observer

7 May 2018 Astronomy Now

NASA’s Rossi X-ray Timing Explorer, decommissioned in 2012, fell back into the atmosphere and burned up 30 April, finally bringing a remarkably successful mission to study black holes and neutron stars to a fiery end.

Astronomers locate isolated neutron star beyond our galaxy

9 April 2018 Astronomy Now

New images from ESO’s Very Large Telescope in Chile and other telescopes reveal a rich landscape of stars and glowing clouds of gas in one of our closest neighbouring galaxies, the Small Magellanic Cloud. The pictures have allowed astronomers to identify an elusive stellar corpse buried among filaments of gas left behind by a 2000-year-old supernova explosion.

Mind the gap: ‘Rapid Burster’ behaviour explained

7 February 2017 Stephen Clark

Scientists observing a curious neutron star in a binary system known as the ‘Rapid Burster’ may have solved a forty-year-old mystery surrounding its puzzling X-ray bursts. They discovered that its magnetic field creates a gap around the star, largely preventing it from feeding on matter from its stellar companion.
