Description
We investigate the masses and radii of neutron stars within the framework of the in-medium modified chiral soliton model, considering the effects of surrounding baryonic environment on the properties of in-medium baryons. The equation of state describing an infinite and asymmetric nuclear matter are obtained by introducing the density-dependent functions. To extrapolate the high density and highly isospin asymmetric region, we study the masses and radii of neutron stars. The results predict the masses and radii to be 1.4$M_{\bigodot}$ and 2$M_{\bigodot}$, respectively. We discuss the physical meaning of the equation of state obtained from the chiralsolitonic approach, based on the present results.
