We have calculated the equation of state of the neutron star
matter and some of its properties for a wide range of
nucleon-nucleon potentials using the lowest order constrained
variational (LOCV) method. It turns out that for the
UV14+TNIpotential, the proton fraction exhibits
a peak and falls off at high densities. The equation of state with
the UV14+TNIpotential is seen to be much harder
than those with other potentials. The polytropic behaviour of the
neutron star matter with various potentials are discussed.
Compared with the other methods, the LOCV results show good
agreement for densities below 0.7 fm−3. Above this
density, however, the differences with other methods are
appreciable.
