Like any substance, neutron stars have an equation of state, or more precisely a phase diagram, such as that for water. The properties of a neutron star are determined by quantum chromodynamics ...

By analyzing the "long ringdown" phase—a pure-tone signal emitted by the post-merger remnant—they have found a strong correlation between the signal's properties and the equation of state of ...

Professor Claudia Ratti explains about quarks and gluons, including the so-called Quark-Gluon Plasma, plus Quantum Chromodynamics ...
