When a very massive star dies, its core contracts. In a supernova explosion, the star’s outer layers are expelled, leaving behind an ultra-compact neutron star. For the first time, the LIGO and Virgo ...

A team of researchers from the Massachusetts Institute of Technology used Frontier to chart the isospin density of a neutron star over a range of conditions. This illustration depicts isospin-dense ...

A neutrino moves through a gas of neutrons and is sensitive to correlations in spin and density in the neutron matter. These correlations determine how much energy transfers from the neutrino to the ...

For astrophysicists, neutron stars stand out as objects of irresistible fascination - perhaps, in part, because of how difficult they are to decipher. But calculations conducted on the Frontier ...

Atoms are made of three things: protons, neutrons, and electrons. Electrons are a type of fundamental particle, but protons and neutrons are composite particles made of up and down quarks. Protons ...

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests. When you purchase through links on our site, we may ...
