Effects of the symmetry energy slope on magnetized neutron stars
Luiz L. Lopes, Cesar V. Flores, Débora P. Menezes
In this work, we study the effect of the symmetry slope on the observables of weakly and strongly magnetized neutron stars within the chaotic magnetic field approximation. We inves…
Probing the Black Hole Interior with Holographic Entanglement Entropy and the Role of AdS/BCFT Correspondence
Fabiano F. Santos
This work explores the black hole information loss paradox, a fundamental challenge in theoretical physics. It proposes insights using Holographic Entanglement Entropy (HEE) and th…
White dwarf structure in gravity: beyond the Chandrasekhar mass limit
Edson Otoniel, Juan M. Z. Pretel, Clésio E. Mota +3
In this work, we investigate the relativistic structure of white dwarfs (WDs) within the framework of modified gravity theory , which introduces a non-mi…
Oscillatory properties of strange quark stars described by the vector MIT bag model
Luiz L. Lopes, Jose C. Jimenez, Luis B. Castro +1
We investigated the radial and non-radial fundamental () mode oscillations of self-bound (quark) stars obtained after employing the Vector MIT (vMIT) bag model. Within this mode…
Universal energy and magnetisation distributions in the Blume-Capel and Baxter-Wu models
A. R. S. Macedo, J. A. Plascak, A. Vasilopoulos +3
We analyse the probability distribution functions of the energy and magnetisation of the two-dimensional Blume-Capel and Baxter-Wu models with spin values in…

This study explores the behavior of compact stars within the framework of gravity, focusing on the functional form . The modified Tolman-Oppenh…
Fluid pulsation modes and tidal deformability of anisotropic strange stars in light of the GW event
José D. V. Arbañil, Cesar V. Flores, César H. Lenzi +1
The effects of the anisotropy on the fluid pulsation modes adopting the so-called Cowling approximation and tidal deformability of strange quark stars are investigated by using the…
Imprints of the nuclear symmetry energy slope in gravitational wave signals emanating from neutron stars
Luiz L. Lopes, Victor B. T. Alves, César O. V. Flores +1
We investigate possible traces of the nuclear symmetry energy slope () in the gravitational wave emission of neutron stars. For fixed stellar mass values, we examine how the slo…
Hybrid stars with reactive interfaces: analysis within the Nambu-Jona-Lasinio model
C. H. Lenzi, G. Lugones, C. Vasquez
It has been shown recently that quark-hadron conversions at the interface of a hybrid star may have a key role on the dynamic stability of the compact object. In this work we perfo…
