Boson stars and oscillatons: A review

L Visinelli - International Journal of Modern Physics D, 2021 - World Scientific
Compact objects occupy a pivotal role in the exploration of Nature. The interest spans from
the role of compact objects in astrophysics to their detection through various methods …

Dynamical boson stars

SL Liebling, C Palenzuela - Living Reviews in Relativity, 2023 - Springer
The idea of stable, localized bundles of energy has strong appeal as a model for particles. In
the 1950s, John Wheeler envisioned such bundles as smooth configurations of …

A study of anisotropic spheres in f (Q) gravity with quintessence field

S Mandal, G Mustafa, Z Hassan, PK Sahoo - Physics of the Dark Universe, 2022 - Elsevier
This manuscript examines the compact stars in gravity f (Q), where non-metricity Q drives
gravitational interactions. To achieve this goal, we consider a spherically symmetric …

Physically viable solutions of anisotropic spheres in gravity satisfying the Karmarkar condition

G Mustafa, MF Shamir, X Tie-Cheng - Physical review D, 2020 - APS
This paper is devoted to discussing compact stars in f (R, G) gravity, where R and G denote
the Ricci scalar and Gauss-Bonnet invariant, respectively. To meet this aim, we consider …

Rotating dark matter admixed neutron stars

J Cronin, X Zhang, B Kain - Physical Review D, 2023 - APS
We study rotating compact stars that are mixtures of the ordinary nuclear matter in a neutron
star and fermionic dark matter. After deriving equations describing a slowly rotating system …

Dynamical evolution of dark matter admixed neutron stars

T Gleason, B Brown, B Kain - Physical Review D, 2022 - APS
We dynamically evolve for the first time dark matter admixed neutron stars with fermionic
dark matter. These systems are mixtures of the ordinary nuclear matter of a neutron star and …

A study of anisotropic spheres in modified gravity via embedding approach

A Ashraf, Z Zhang, A Ditta, G Mustafa - Annals of Physics, 2020 - Elsevier
The motivation of this paper is based on the foundation of extended teleparallel gravity with
matter coupling to prospect the accelerated expansion of the Universe. This theory based on …

Realistic solutions of fluid spheres in f (G, T) Gravity under Karmarkar condition

G Mustafa, X Tie-Cheng, MF Shamir - Annals of Physics, 2020 - Elsevier
This manuscript investigates the compact stars solutions in the background of observational
data (radii and mass) by employing the Karmarkar condition under the f (G, T) modified …

A conjecture on the minimal size of bound states

B Freivogel, T Gasenzer, A Hebecker, S Leonhardt - SciPost Physics, 2020 - scipost.org
We conjecture that, in a renormalizable effective quantum field theory where the heaviest
stable particle has mass $ m $, there are no bound states with radius below $1/m $(Bound …

Charged anisotropic Bardeen spheres admitting conformal motion

MF Shamir, G Mustafa - Annals of physics, 2020 - Elsevier
Symmetries can play a vital role to develop the natural relation between geometry and
matter through the Einstein field equations. The main purpose of this paper is to propose a …
