Earth-based analogs are opening new frontiers in studies of the superdense interiors of neutron stars

PSR J0952-0607, a so-called millisecond pulsar, has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into the heaviest neutron star observed to date.

The supernova has astonished experts since its discovery almost four decades ago

Astronomers using the MeerKAT radio telescope in South Africa have observed a neutron-star jet with an S shape for the first time. The post Neutron-star jet sprays like a garden sprinkler first appeared on EarthSky.

Neutron stars typically rotate at fast speeds, taking just seconds or even a fraction of a second to fully spin on their axis.

A new collaboration between quantum physicists and astronomers has revealed that neutron stars could be supersolids, which could explain why they randomly speed up.

So far, little is known about the interior of neutron stars, those extremely compact objects that can form after the death of a star. The mass of our sun or even more is compressed into a sphere with the diameter of a large city. Since their discovery more than 60 years ago, scientists have been trying to decipher their structure.

Through extensive model calculations, physicists at Goethe University Frankfurt have reached general conclusions about the internal structure of neutron stars, where matter reaches enormous densities: depending on their mass, the […]

Solar System's moons such as Europa or Enceladus have thin crusts over deep oceans while the planet Mercury has a thin crust over a large metallic core.

From LIGO, there weren't enough neutron star-neutron star mergers to account for our heavy elements. With a JWST surprise, maybe they can.

A collaboration between quantum physicists and astrophysicists, led by Francesca Ferlaino and Massimo Mannarelli, has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic cosmic phenomenon with ultracold dipolar atoms. This research, now published in Physical Review Letters, establishes a strong link between quantum mechanics and…

Interpreting high-energy, astrophysical phenomena, such as supernova explosions or neutron-star collisions, requires a robust understanding of matter at supranuclear densities. However, our knowledge about dense matter explored in the cores of neutron stars remains limited. Fortunately, dense matter is not only probed in astrophysical observations, but also in terrestrial heavy-ion collision experiments. In this…

Astronomers have observed the most massive known example of an object called a neutron star, one classified as a "black widow" that got particularly hefty by...

Where do the heaviest elements in the Universe come from? If you were like most astrophysicists during the 20th century, you might've said from supernova explosions: stellar cataclysms that occur…

PSR J0952-0607, a so-called millisecond pulsar, has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into the heaviest neutron star observed to date.

Neutron stars are the remnants of old stars that have run out of nuclear fuel and undergone a supernova explosion and a subsequent gravitational collapse. Although their collisions—or binary mergers—are rare, when they do occur, these violent events can perturb spacetime itself, producing gravitational waves detectable on Earth from hundreds of millions of light years away.

Astronomers have detected the millimeter afterglow of a short-duration gamma-ray burst, a fiery explosion caused by the merger of a neutron star with another star.

Astronomers have discovered an ultra-long-period radio-emitting neutron star, PSR J0901-4046, with spin properties distinct from the known neutron stars.
