Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

Neutron stars, the remnants of massive stars after a supernova, are among the densest and most fascinating objects in the universe. Recent discoveries have indicated that some neutron stars are ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such ...

The transformation of neutrinos in a neutron star merger could be crucial to shaping the way events of the collision unfold. For the first time, a team of physicists has simulated how neutrinos change ...

Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...
