Polytropic fits of modern and unified equations of state

Equations of state for a cold neutron star's interior are presented in three-column tables that relate the baryonic density, energy and pressure. A few analytical expressions those have been established these past two decades, as convenient way to present large number nuclear models star matter. Some representations based on nonunified equations state, sense high low density part not computed with same model. Fits piecewise polytropic representation revised by using unified is say which calculated consistently core crust. set 52 chosen. Each one divided seven polytropes via an adaptive segmentation, parameters per polytrope fitted tabulated equation state. The total mass, radius, tidal deformability moment inertia stars modelled from fits compared quantities original ensure accuracy macroscopic parameters. We provide 15 nucleonic relativistic mean field models, hyperonic five hybrid mean-field 24 Skyrme ab initio fit error small well within estimated measurement current next generation telescopes.
