Estimating the Role of Bag Constant and Modified Theory on Anisotropic Stellar Models
Tayyab Naseer, M. Sharif
In this article, we are devoted to discuss different compact stars admitting anisotropic interiors in a particular modified theory of gravity. For this purpose, a spherically symme…
Magnetized particle motion and accretion process with shock cone morphology around a decoupled hairy black holes
G. Mustafa, Faisal Javed, S. K. Maurya +5
Relativistic accretion onto compact objects such as black holes and neutron stars is one of the most efficient known mechanisms for converting gravitational potential energy into r…
Analytical and numerical study of accretion processes around charged spherically symmetric black holes in scalar-tensor Gauss-Bonnet gravity
G. Mustafa, O. Donmez, A. Errehymy +5
We investigate the physical phenomena occurring around a spherically symmetric, non-rotating charged black hole (BH) to explore the effects of scalar-tensor Gauss-Bonnet gravity on…
Physical Existence of Relativistic Stellar Models within the context of Anisotropic Matter Distribution
M. Sharif, Tayyab Naseer, Hira Shadab
Two distinct non-singular interior models that describe anisotropic spherical configurations are presented in this work. We develop the Einstein field equations and the associated…
Modeling Gravastar Structure admitting Kuchowicz Spacetime in Rastall Gravity Theory
Tayyab Naseer, M. Sharif, Areej Tabassum
This paper investigates the gravastar model as a potential alternative to black holes, utilizing the Kuchowicz metric in the context of Rastall gravity. The model comprises three d…
Role of Non-conserved Gravity Theory and Electric Charge in Constructing Complexity-free Stellar Models: A Novel Approach under Non-minimal Coupling
Tayyab Naseer
This study explores the application of complexity factor within the context of Rastall gravity, exploring its implications on a static spacetime admitting spherical symmetry associ…
