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 ...

State symbols are used in symbol equations to show whether each chemical is a solid, liquid, gas or solution. But it’s often hard to know exactly what’s going on. We can use word equations to ...

When researchers compare these experiments to neutron-star observations, they can calculate the equation of state (EOS) of particles interacting in low-temperature, dense environments. The EOS ...
