Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The density of such matter is equivalent to compressing around 100,000 Eiffel Towers ...

"Measuring the properties of neutron-star matter is indeed very hard and this is because while we can measure the mass of a neutron star very accurately, it is very hard to measure its radius ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars are the leftover cores of exploded stars and the densest known material in the ...

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 ...
