Thin-shell wormholes in cosmic voids

Jonathan A. Rebouças, Edson Otoniel, Francisco S. N. Lobo

Cosmic voids are underdense regions that can provide an effective large-scale environment with a de Sitter-like gravitational behavior. Motivated by recent black-hole solutions emb…

Modified electron dispersion relations in degenerate white dwarfs

Edson Otoniel, Iarley P. Lobo

We investigate how modified electron dispersion relations affect the structure of cold white dwarfs (WDs). The deformation is introduced only in the degenerate electron equation of…

Rotating strange dwarfs and their indistinguishability from white dwarfs

Edson Otoniel, José D. V. Arbañil, Geanderson A. Carvalho +1

We investigate the structure of strange dwarfs, modeled as hybrid compact stars composed of a self bound strange quark matter core surrounded by a white dwarf like crust, within a…

Quantum improved wormholes in the Dekel-Zhao dark matter halo

Jonathan A. Rebouças, Celio R. Muniz, Francisco Bento Lustosa +1

This work presents and investigates novel traversable wormhole solutions within the framework of Asymptotically Safe Gravity (ASG), sourced by a dark matter halo modeled by the Dek…

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…

Electronic states in a bilayer graphene quantum ripple

M. C. Araújo, A. C. A. Ramos, J. Furtado

In this paper, we investigate the influence of the geometry in the electronic states of a quantum ripple surface. We have considered an electron governed by the spinless stationary…
