Abstract

Ad-hoc parametrized Tolman-Oppenheimer-Volkoff (PTOV) equations proposed by Velten, Oliveira, and Wojnar can be correctly derived from the Einstein field equation with a modified matter with anisotropic pressure and effective energy density. The advantage of the latter form of PTOV is we can derive other properties of neutron star beyond static and spherical symmetric properties such as moment inertia and tidal deformation. Here we show that the corresponding pressures, energy density, and speed of sound profiles of modified energy-momentum tensor obey the energy conditions.
