Epicyclic motion of charged particles around a weakly magnetized Kiselev black hole

TL;DR

This paper studies the dynamics of charged particles around a magnetized Kiselev black hole, focusing on bound orbits, epicyclic frequencies, and precession effects in a weak magnetic field.

Contribution

It introduces analysis of combined quintessence and magnetic fields on particle motion and orbital precession in this specific black hole spacetime.

Findings

Bound motion and stable circular orbits are characterized.

Impact of magnetic and quintessence fields on epicyclic frequencies is analyzed.

Differences in periapsis shift and Larmor precession from other spacetimes are identified.

Abstract

We investigate the motion of charged particles evolving around a magnetized Kiselev black hole, in the weak magnetic field approximation. The effective potential allows us to study the bound motion and the stable circular orbits. We analyze the impact of combined quintessence and magnetic fields on the epicyclic frequencies. Finally, we examine the periapsis shift and gravitational Larmor precession pointing out differences from the Ernst or Kiselev spacetimes.
