A “beautiful effect” predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar – a neutron star featuring a powerful magnetic fie...
An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips u...
Russia's Rosatom and China's Atomic Energy Authority (CAEA) have signed a Comprehensive Programme for Long-Term Cooperation in the field of fast-neutron reactors and closing the nuclear fuel cycle.
LIGO-Virgo finds mystery object in gap between neutron stars and black holes（图）
LIGO-Virgo mystery object gap between neutro holes
2020/7/3
When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive die, they explode in supernovas and leave behind dense, dead...
On April 25, NSF's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears to be a crash between two neutron s...

Radio Observations Point Likely Explanation Neutron-Star Merger
2018/1/10
Three months of observations with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have allowed astronomers to zero in on the most likely explanation for what happened in the af...
LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars（图）
LIGO Virgo first detection gravitational waves produced colliding neutron stars
2017/10/26
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...

Radio Eyes Unlocking Neutron-Star Collision
2017/10/26
When a pair of superdense neutron stars collided and potentially formed a black hole in a galaxy 130 million light-years from Earth, they unleashed not only a train of gravitational waves but also an ...

Neutron Stars Strike Back Black Holes Jet Contest
2015/8/13
Some neutron stars may rival black holes in their ability to accelerate powerful jets of material to nearly the speed of light, astronomers using the Karl G. Jansky Very Large Array (VLA) have discove...
NEWPORT NEWS, VA, October 16, 2014 – Like dancers swirling on the dance floor with bystanders looking on, protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, ...

Using a technique that exploits general relativity, astronomers in the US and the Netherlands have identified a neutron star that has a mass nearly twice that of the Sun. The object is the most massiv...
Physicists in Canada and the UK have had a rare glimpse at the atmosphere of a neutron star just 330 years after it was formed in a violent explosion. Instead of resembling more mature neutron stars, ...
Mountains on neutron stars could boost gravitational wave detection（图）
mountains neutron stars gravitational wave detection
2009/5/22
Astrophysicists looking for gravitational waves should set their sights on mountainous neutron stars, according to a new numerical study by researchers in the US. The study also suggests that the crus...
