To predict the properties of matter in a neutron star, physicists consider a theoretical model that consists of an infinite system of pure neutrons that interact by the strong nuclear force. This allows them to calculate the neutron matter equation of state and thus how much weight the star can support before gravity crushes it into a black hole.

Researchers leveraged data from nuclear scattering experiments to make stringent constraints on how neutrons and protons arrange themselves in the nucleus. Their predictions are tightly connected to how large neutron stars grow and what elements are likely synthesized in neutron star mergers.
