Spin and Isospin Asymmetry, Equation of State and Neutron Stars

Abstract

In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry sti ens the equation of state and leads to high mass for the neutron star.
