| Abstract: | We study the effects of energy-momentum squared gravity (EMSG) on the properties and behaviour of neutron stars (NSs) with the variation of the free parameter, $\alpha$. We derive the hydrostatic equilibrium equations in EMSG and solve them numerically to obtain the neutron star mass-radius relations for soft, stiff, and intermediate equations of state (EOS). We use the existing observational measurements of the masses and radii of NSs to constrain the tidal deformability, compactness, and $f$-mode frequency of the NS model. We find that the Stiff EOS undergoes the phase transition at the highest energy densities and pressures, followed by the Intermediate and Soft EOSs, demonstrating the differing characteristics of these models. This behaviour allows us to compare the effect of the chosen EOS on the star's sound speed profile, reaffirming the physical validity of the models across different parameter values. |
