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…

The dynamics of S-stars and G-sources orbiting a supermassive compact object made of fermionic dark matter
Valentina Crespi, Carlos R. Argüelles, Eduar A. Becerra-Vergara +4
Surrounding Sgr A*, a cluster of young and massive stars coexist with a population of dust-enshrouded objects, whose astrometric data can be used to scrutinize the nature of Sgr A*…

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…
