Lorentz Symmetry Breaking Traversable Wormhole Models Supported by Einasto Dark Matter
Rana Muhammad Zulqarnain, M. Yousaf, Allah Ditta +3
We investigate static, spherically symmetric traversable wormholes in Kalb Ramond gravity, where spontaneous Lorentz symmetry breaking arises from a non-vanishing vacuum expectatio…
Transient Dynamical Wormholes with Decaying Radial Energy Flux
Allah Ditta, Phongpichit Channuie
We investigate a class of time-dependent traversable wormholes within the framework of general relativity by allowing the shape function to vary with time. In this setting, the evo…
Relativistic accretion process onto rotating black holes in Einstein-Euler-Heisenberg nonlinear electrodynamic gravity
Orhan Donmez, G. Mustafa, Himanshu Chaudhary +4
In this study, we uncover the accretion dynamics and oscillatory behavior around rotating black holes within the EEH nonlinear electrodynamic framework by analyzing both the motion…
Structure and Mass-Radius Stability of Charged Compact Objects in Symmetric Teleparallel Euler-Heisenberg Gravity
Allah Ditta, M. Yousaf, G. Mustafa +4
In this work, we develop a new relativistic model for a charged anisotropic compact star in the framework of modified symmetric teleparallel gravity, namely -Euler-Heisenberg…
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…
Traversable Wormholes in non-minimal Einstein-Yang-Mills Gravity: Geometry, Energy Conditions, and Gravitational Lensing
Jureeporn Yuennan, Allah Ditta, Thammarong Eadkhong +1
This work presents a new class of static, spherically symmetric traversable wormhole solutions within the framework of non-minimal Einstein-Yang-Mills (EYM) gravity, where the SU(2…
