Abstract:
The equations of state (EoS) of relativistic asymmetric nuclear matter
are obtainable from assumed form of the interaction Lagrangian. They are
one of important inputs to describe the neutron stars. The structure of
the neutron stars, i.e. the density of matter and the pressure as
functions of radial distance starting from their values at the center of
a star, is straightforwardly dependent on EoS. Similarly, a limitation
on the total mass of the neutron star can be obtained therefrom. Thus,
EoS and the underlying nucleon interactions can be tested also by the
means of astronomical observations.
