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 chiral solitonic approach, based on the present results.
