Dark Matter in White Dwarfs: Implications for Their Structure
Sílvia P. Nunes, José D. V. Arbañil, Juan M. Z. Pretel +1
White Dwarfs (WDs), the final evolutionary stage of most stars, are frequently modeled considering only a dense plasma matter. However, their potential interaction with dark matter…
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…
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…
Self-bound hybrid stars with strong phase transitions can relieve major compact star observation tensions
Chen Zhang, Juan M. Z. Pretel, Renxin Xu
Some recent pulsar observations cannot naturally fit into the conventional picture of neutron stars: the compact objects associated with HESS J1731-347 and XTE J1814-338 have too s…
White dwarfs in regularized 4D Einstein-Gauss-Bonnet gravity
Juan M. Z. Pretel, Takol Tangphati, İzzet Sakallı +1
White dwarfs (WDs), as the remnants of low to intermediate-mass stars, provide a unique opportunity to explore the interplay between quantum mechanical degeneracy pressure and grav…
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…
