Charged anisotropic models with complexity-free condition

M Sharif, T Naseer - Annals of Physics, 2023 - Elsevier
This paper uses the definition of complexity for a static spherically symmetric spacetime and
extends it to the case of charged distribution. We formulate the Einstein–Maxwell field …

Dynamical instability and expansion-free condition in gravity

I Noureen, M Zubair - The European Physical Journal C, 2015 - Springer
A dynamical analysis of a spherically symmetric collapsing star surrounded by a locally
anisotropic environment under an expansion-free condition is presented in f (R, T) f (R, T) …

Dynamical instability of the charged expansion-free spherical collapse in gravity

Mechanical stability of cylindrical thin-shell wormholes

M Sharif, M Azam - The European Physical Journal C, 2013 - Springer
In this paper, we apply the cut and paste procedure to the charged black string for the
construction of a thin-shell wormhole. We consider the Darmois–Israel formalism to …

Charged anisotropic spherical collapse in f (R, T, Q) gravity

M Sharif, T Naseer - Chinese Journal of Physics, 2023 - Elsevier
This paper discusses the gravitational collapse of dynamical self-gravitating fluid distribution
in f (R, T, Q) gravity, where Q= R φ ϑ T φ ϑ. In this regard, we assume a charged anisotropic …

Radiating composite stars with electromagnetic fields

SD Maharaj, BP Brassel - The European Physical Journal C, 2021 - Springer
We derive the junction conditions for a general spherically symmetric radiating star with an
electromagnetic field across a comoving surface. The interior consists of a charged …

Stability analysis of thin-shell wormholes from charged black string

M Sharif, M Azam - Journal of Cosmology and Astroparticle …, 2013 - iopscience.iop.org
In this paper, we construct thin-shell wormholes from charged black string through cut and
paste procedure and investigate its stability. We assume modified generalized Chaplygin …

Expansion-free cylindrically symmetric models

M Sharif, Z Yousaf - Canadian Journal of Physics, 2012 - cdnsciencepub.com
This paper investigates cylindrically symmetric distribution of an anisotropic fluid under the
expansion-free condition, which requires the existence of a vacuum cavity within the fluid …

Electromagnetic field and dynamical instability of cylindrical collapse in f(R) gravity
