Ferromagnetism in neutron matter and its implication for the neutron star equation of state
Abstract
We investigate the possible contribution of the ferromagnetic phase of neutron matter in the neutron star interior to the star's magnetic field. We introduce a relativistic, selfconsistent calculation of the ferromagnetic phase in neutron matter within the context of the relativistic meanfield approximation. The presence of the ferromagnetic phase stiffens the star's equation of state which implies a larger neutron star radius compared to the nonferromagnetic case.

The equation of state of neutron matter, symmetry energy and neutron star structure
We review the calculation of the equation of state of pure neutron matter using quantum Monte Carlo (QMC) methods. QMC algorithms permit the study of manybody nuclear systems using realistic twoand threebody forces in a nonperturbative framework. We present the results for the equation of state of neutron matter, and focus on the role of threeneutron forces at supranuclear density. We discuss the correlation between the symmetry energy, the neutron star radius and the symmetry energy. We also combine QMC and theoretical models of the threenucleon interactions, and recent neutron star observations to constrain the value of the symmetry energymore » 
Neutron star properties and the equation of state of neutronrich matter
We calculate total masses and radii of neutron stars for pure neutron matter and nuclear matter in {beta} equilibrium. We apply a relativistic nuclear matter equation of state derived from DiracBruecknerHartreeFock calculations. We use realistic nucleonnucleon interactions defined in the framework of the meson exchange potential models. Our results are compared with other theoretical predictions and recent observational data. Suggestions for further study are discussed. 
Polarization effects in the equation of state for neutron star matter
A new method is given for calculating the equation of state for dense neutron matter taking into consideration the polarization of the medium around a quasiparticle within Landau's theory of normal Fermi liquids. It is found that polarization effects make the matter more incompressible. (auth)
