Origin of Quasi-Periodic Oscillations and Accretion Process in X-Ray Binaries around Quantum Lee-Wick Black Hole
Orhan Donmez, G. Mustafa, M. Yousaf +3
In this study, we investigate the accretion dynamics and test particle motion around a non-rotating, spherically symmetric Lee-Wick black hole (BH) to reveal how the model paramete…

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…
