Bayesian constraints on quadratic gravity from the ADM mass of white dwarfs
Edson Otoniel, Lucas A. Souza, Lucas A. Sousa +3
We calculate static equilibrium sequences for white dwarfs (WDs) in quadratic symmetric teleparallel gravity, f(Q)=Q+alpha Q^2, and perform a Bayesian comparison between the negati…
Junction Conditions, Radial Stability, Thermodynamics, Optical Geometry and Appearance of Polymer-Quintessence Thin-Shell Wormholes
Jonathan A. Rebouças, Edson Otoniel, M. C. Araújo +2
The authors construct a reflection‑symmetric thin‑shell wormhole from a polymer‑corrected black‑hole metric surrounded by Kiselev‑type quintessence and examine its junction conditi…
Fermi Acceleration Mechanisms Beyond Lorentz Symmetry
Gilson A. Ferreira, Erick Aguiar, A. A. Araújo Filho +3
The authors construct models of first- and second-order Fermi acceleration that include generic frame transformations, dispersion relations, and conservation laws, and study how de…
Thin-shell wormholes in cosmic voids
Jonathan A. Rebouças, Edson Otoniel, Francisco S. N. Lobo
The paper constructs symmetric thin‑shell wormholes by joining two copies of a black‑hole region inside a cosmic void, derives the shell’s stress‑energy via Darmois‑Israel junction…
Thin-Shell Wormholes from Entropy-Induced Black-Hole Geometries
Jonathan A. Rebouças, Edson Otoniel
Modified black-hole entropies can induce effective spacetime geometries and thereby provide a thermodynamic route for investigating thin-shell wormholes. In this work, we construct…
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-m…
