We investigate exotic stars composed of dark energy within the context of Einstein's General Relativity, by applying an extended Chaplygin gas equation-of-state. To account for anisotropies, we utilize a formalism based on the complexity factor to obtain numerical solutions. By applying well-established criteria, we demonstrate that the solutions are physically valid and well-behaved. In addition, a comparison with a more conventional approach is also conducted.

  1. On Modeling Anisotropic Quark Stars: The Role of Anisotropy in Radial Oscillation Spectra

    gr-qc 2026-08 conditional novelty 6.0 of 10

    Radial oscillation spectra of an anisotropic strange quark star model of Cen X-3 are computed for three anisotropy prescriptions and differ by up to 40 percent between models.

  2. 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.
