On the Stability of Anisotropic Neutron Stars
L. M. Becerra, E. A. Becerra-Vergara, F. D. Lora-Clavijo +1
We model anisotropic neutron stars using three distinct prescriptions for pressure anisotropy, the Horvat, Bowers-Liang, and Covariant models, and three equations of state with dif…

Rotating neutron stars: anisotropy model comparison
L. M. Becerra, E. A. Becerra-Vergara, F. D. Lora-Clavijo
We build slowly rotating anisotropic neutron stars using the Hartle-Thorne formalism, employing three distinct anisotropy models--Horvat, Bowers-Liang, and a covariant model--to ch…

Neutron stars in the generalized SU(2) Proca theory
Jhan N. Martinez, Jose F. Rodriguez, Laura M. Becerra +2
The generalized SU(2) Proca theory is a vector-tensor modified gravity theory characterized by an action that remains invariant under both diffeomorphisms and global internal trans…
