In this work we obtain an anisotropic neutron star solution by gravitational decoupling starting from a perfect fluid configuration which has been used to model the compact object PSR J0348+0432. Additionally, we consider the same solution to model the Binary Pulsar SAX J1808.4-3658 and X-ray Binaries Her X-1 and Cen X-3 ones. We study the acceptability conditions and obtain that the MGD--deformed solution obey the same physical requirements as its isotropic counterpart. Finally, we conclude that the most stable solutions, according to the adiabatic index and gravitational cracking criterion, are those with the smallest compactness parameters, namely SAX J1808.4-3658 and Her X-1.

  1. Coherent quantum hairy black holes from gravitational decoupling: regularity, geodesics, and scalar ringdown

    hep-th 2026-02 conditional novelty 6.0

    Gaussian-smearing the gravitational-decoupling hairy black hole produces a regular core and modified photon rings, lensing, and a claimed but absent ringdown spectrum.

  2. Light Deflection due to Spinoptic Effects in Parametrized and Spherically Symmetric Hairy Black Holes

    gr-qc 2026-05 unverdicted novelty 4.0

    Spinoptics calculations show parameter-dependent out-of-plane deflection angles for light in RZ and hairy black hole spacetimes, with assessment of mimicry between the models.

  3. Gravitational decoupling and regular hairy black holes: Geodesic stability, quasinormal modes, and thermodynamic properties

    gr-qc 2025-12 conditional novelty 4.0

    For the regular hairy black hole metric (29), larger β shrinks the ISCO and photon sphere, reduces QNM damping, and adds a canonical-ensemble stable phase.
