Abstract

We investigate the impact of hyperon and dark matter on macroscopic properties of neutron stars, including mass, radius, gravitational redshift, and moment of inertia, within the framework of relativistic mean field theory. Our findings reveal that the absorbing of hyperon and dark matter components significantly softens the equation of state of neutron star. Dark matter Fermi momentum varies between 0 and 0.06 GeV, and all types of neutron stars yield to the current observational constraints with dark matter Fermi momentum being \(k_{f}^{DM}=0.03\text{ GeV}\). In addition, both hyperons and dark matter increase the gravitational redshift while decreasing the moment of inertia. Lastly, we present the linear relationships between mass, gravitational redshift and moment of inertia that can further assist in identifying neutron star types.
