abstract

In the present article, we have constructed static anisotropic compact star models of Einstein field equations for the spherical symmetric metric of embedding class one. By assuming the particular form of metric function $\nu$, We have solved the Einstein field equations for anisotropic matter distribution. The anisotropic models are representing the realistic compact objects such as SAX J 1808.4-3658 (SS1), Her X - 1, Vela X-12, PSR J1614-2230 and Cen X - 3. We have reported our results in details for compact star Her X-1 on the ground of physical properties such as pressure, density, velocity of sound, energy conditions, TOV equation and red-shift etc. Along with these, we have also discussed about stability of the compact star models. Finally we made the comparison between our anisotropic stars with the realistic objects on the key aspects as central density, central pressure, compactness and surface red-shift.

  1. Radial Oscillations of the HESS J1731-347 Compact Object via the Karmarkar Condition in Gravity

    gr-qc 2025-04 conditional novelty 5.0 of 10

    A Karmarkar-based anisotropic stellar model fits HESS J1731-347's mass and radius and predicts radial oscillation frequencies about 20-30% higher than the isotropic Tolman IV model.
