NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories ...

Researchers study neutron star crusts by simulating neutron matter then adding “hidden” neutrons to mediate interactions between “real” neutrons. Next, neural networks construct a quantum wave ...

For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of ...

A team of astronomers, including Danai Antonopoulou and Anna Watts from the University of Amsterdam, has discovered that sudden speed jumps in the rotational velocity of pulsars have a minimum size, ...

Ultra-dense corpses of former stars, known as neutron stars, spin very, very fast. They also sometimes “glitch,” or speed up for no reason. A team of European quantum physicists and astronomers ...
