Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons ...

New theoretical analysis places the likelihood of massive neutron stars hiding cores of deconfined quark matter between 80 and 90 percent. The result was reached through massive supercomputer runs ...

The universe may contain extremely dense and exotic hypothetical cosmic objects known as strange quark stars. While astrophysicists continue to debate quark stars' existence, a team of physicists has ...

Quark stars are one of the wildest ideas in astronomy—objects so dense that even neutrons may break apart into free quarks. If they exist, they could represent an extreme “in-between” state, sitting ...

Ground-based radio telescopes, gravitational wave detectors, and a space-based X-ray telescope (right) all measure neutron stars (top left, shown merging), lending insight into the pairing of ...

Quark matter may join solid, liquids, gases, and plasmas as a newly-understood state of matter. Far from being exotic, a new study suggests that quark matter could make up a large percentage of the ...

"It is fascinating to concretely see how each new neutron-star observation enables us to deduce the properties of neutron-star matter with increasing precision." When you purchase through links on our ...
