| Abstract | The relativistic mean field (RMF) model is considered as one of the best methods to study the nuclear system that has a high degree of isospin asymmetry and baryon density. In the present contribution, we take 25 well-known parameter sets of the RMF model to discuss the parametric dependence of the neutron and hyperon star properties. Various properties of the canonical star are discussed and only a few parameter sets are found to satisfy both the astrophysical and nuclear matter constraints. We add both and ?* strange mesons to the ?-?-? model. Effects of the -meson on the equation of state and maximum mass of the hyperon star are discussed in detail. -meson affects the threshold density of hyperon production and pushes the hyperon production to a higher density. Effects of the hyperon?meson coupling constants on the maximum mass?radius profile and strangeness content of the hyperon star are discussed in the ?-?-?--?* model. |
