The structure of neutron stars is considered from theoretical and observational perspectives. We demonstrate an important aspect of neutron star structure: the neutron star radius is primarily determined by the behavior of the pressure of matter in the vicinity of nuclear matter equilibrium density. In the event that extreme softening does not occur at these densities, the radius is virtually independent of the mass and is determined by the magnitude of the pressure. For equations of state with…

Neutron stars and the equation of state of dense matter
Neutron star radii provide useful information about the equation of state of neutron-rich matter. Particularly interesting is the density dependence of the equation of state (EOS). For example, the
