Nucleon spectra and wave functions from holographic models with dual Einstein-dilaton and Starobinsky-dilaton gravities

Adão S. da Silva Junior, Juan M. Z. Pretel, Henrique Boschi-Filho

The paper investigates nucleon mass spectra using two holographic approaches—Einstein‑dilaton and Starobinsky‑dilaton gravity—introducing new parameters to better match experimenta…

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…

Examining the influence of anisotropy on the fundamental mode of nonradial oscillation in neutron stars on a complete general relativistic scheme

José D. V. Arbañil, Gabriel O. Cavalheiro, Victor B. T. Alves +3

The anisotropic influence on the -mode frequency of oscillations and dimensionless tidal deformability of neutron stars is analyzed by employing the nonradial oscillation equati…

Vector mesons from a holographic QCD model in -dilaton gravity

Adão S. da Silva Junior, Juan M. Z. Pretel

In this paper we investigate the spectrum and decay constants of vector mesons based on -dilaton gravity. We focus particularly on the well-known Starobinsky model, given by…

Dark energy stars from the modified Chaplygin gas: universal relations

Krishna Pada Das, Juan M. Z. Pretel

Dark energy stars (DESs), described by the modified Chaplygin gas (MCG), can be dynamically stable and fall within different observational measurements. In this work, we employ div…

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…
