Bayesian constraints on quadratic gravity from the ADM mass of white dwarfs
Edson Otoniel, Lucas A. Sousa, Jonathan A. Rebouças +1
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…
White Dwarf Stellar Structure from Effective Polymer Geometry in Loop Quantum Gravity
Edson Otoniel, Jonathan A. Rebouças, M. C. Araújo +1
We construct an effective Tolman Oppenheimer Volkoff system for cold carbon white dwarfs using the areal radius form of a polymer metric sector motivated by loop quantum gravity. T…
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…
Magnetic pressure anisotropy in ultra-dense white dwarfs: Landau quantization and neutronization effects
Edson Otoniel, Juan M. Z. Pretel, Victor B. T. Alves +2
Strong magnetic fields modify the thermodynamics of white dwarf (WD) matter by quantizing the transverse motion of degenerate electrons into Landau levels and splitting the pressur…
Localized magnetic pressure anisotropy in strange dwarfs with crystalline crusts
Mila Leite Garcia Reis, Daniela Eller Uliana, Jaziel G. Coelho +1
We study equilibrium sequences of magnetized strange dwarfs composed of a self bound MIT bag strange matter core, with \(B_{\rm bag}^{1/4}=145\,{\rm MeV}\), and an ordinary crystal…
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…
