Slowly rotating condensate dark stars beyond the mean-field approximation
Grigoris Panotopoulos, Ãngel Rincón, Ángel Rincón +1
We investigate rotational properties and universal relations of slowly rotating Bose-Einstein condensate dark stars in the context of General Relativity, both at the mean-field lev…
Radial oscillations of quark stars in light of current astrophysical constraints: A comparative study
G. Panotopoulos, A. Rincon, I. Lopes
We investigate the structural and oscillatory properties of isotropic strange quark stars within General Relativity, focusing on three physically motivated equations of state: the…
Rotational Behaviour of Exotic Compact Objects
Zakary Buras-Stubbs, IlÃdio Lopes
We construct exotic compact objects composed entirely of self-interacting asymmetric fermionic dark matter governed by a repulsive Yukawa potential with massive dark interaction bo…
Stellar modeling within regularized 4D Einstein-Gauss-Bonnet gravity in light of current astrophysical constraints
G. Panotopoulos, Ã. Rincón, I. Lopes
In this study we obtain interior solutions and investigate structural properties of isotropic compact stars in the framework of four-dimensional regularized Einstein-Gauss-Bonnet (…
Exploring the Structural Properties of Anisotropic Dark Matter-Admixed Quark Stars
G. Panotopoulos, A. Rincón, I. Lopes
We investigate anisotropic compact stars comprising two non-interacting fluids: quark matter and condensed dark matter. Using the MIT Bag model equation of state for quark matter a…
Screening Mechanisms on White Dwarfs: Symmetron & Dilaton
Joan Bachs-Esteban, IlÃdio Lopes, Javier Rubio
This work provides the first comparison of the symmetron and dilaton fields in white dwarfs. We show how these screening mechanisms behave inside {such stars} and their impact on s…
