Abstract
In order to obtain the properties of compact stellar objects, appropriate equations of state have to be used. In the literature, strange meson fields, namely the scalar meson field ${\sigma}^*(975)$ and the vector meson field $\phi(1020)$, had to be considered in order to reproduce the observed strongly attractive $\Lambda\Lambda$ interaction. The introduction of these strange mesons makes the equations of state harder (EOS) due to the repulsive effect of the $\phi(1020)$ meson. In this work the inclusion of these mesons in the equation of state and their influence on the properties of the neutron stars are investigated.
