Description

This work delves into the exploration of a wormhole within the framework of Beyond Horndeski Theories. Our investigation encompasses the analysis of crucial components such as the effective potential, the structure of the wormhole throat, and the presence of quasi-periodic oscillations. Specifically, we assess how the wormhole affects the frequency characteristics of X-ray quasi-periodic oscillations (QPOs) observed in four X-ray binaries. To provide context, we compare these findings with established results related to upper and lower frequencies derived from the relativistic precession model. Utilizing a Monte Carlo Markov Chain (MCMC) simulation, we rigorously examine the potential impacts of wormhole parameters on the observed X-ray QPOs.
