Neutron star equation of state

The neutron star equation of state describes how matter behaves under the extreme pressures and densities inside a neutron star. It explains how particles, mainly neutrons, arrange themselves and how the star’s internal pressure balances gravity to keep it stable. Think of it as a recipe that tells us how matter responds when squeezed to densities billions of times greater than those on Earth. Understanding this helps scientists predict the star’s properties, like its size and mass, and reveals the fundamental physics of matter under such extraordinary conditions.
