Neutron stars with an anisotropic equation of state: mass, redshift and stability.
Abstract
Summary. Fully relativistic, anisotropic neutron star models are studied by means of several simple or plausible assumptions about the equation of state at high densities. We find that neglecting stability requirements a) there is in principle no limiting mass nor limiting redshift for arbitrarily large anisotropy, b) small deviations from isotropy entail small changes in the mass and redshift of a star, c) estimates with semi-realistic equations of state for neutron star matter show that the maximum mass of a stable neutron star still lies beyond 3-4 M0. Key words: neutron star models equations of state
