Abstract

We investigate the behavior of test particles orbiting a slowly rotating, axially symmetric, charged black hole within the context of Bumblebee gravity theory, with an emphasis on how the parameters of the model impact particle dynamics. This black hole solution is defined by four primary parameters: the mass M, the spin parameter a, the charge Q, and the Lorentz-violating parameter α. We give analytical expressions for the radial profiles of specific energy and specific angular momentum associated with stable circular orbits in the equatorial plane. Also, we utilize the effective potential method to analyze the stability of these orbits and the forces acting on the particles. We compute and discuss the radial and latitudinal harmonic oscillation frequencies where the parameters are the mass M, charge Q, parameter a, and the Lorentz-violating parameter α. We also explore the key characteristics of quasi-periodic oscillations of test particles near stable circular orbits, especially in the equatorial plane. Moreover, we investigate precession effects, including periastron precession and the Lense-Thirring effect. Our results indicate that the motion of particles around the black hole is notably affected by the parameters of the model.
