Charged particles motion and quasiperiodic oscillation in Simpson-Visser spacetime in the presence of external magnetic fields

Original language description

The present work is devoted to the study of the dynamics of charged particles around Simpson-Visser black holes (with the length parameter l &lt;= 2) and wormholes (l &gt; 2) immersed in an external asymptotically uniform magnetic field. To do this, first, we solve the Maxwell equation for 4-potentials of the electromagnetic field and show that the difference between the numerical solution and Wald's solution is small enough to neglect it, which may allow us to use the solution obtained by Wald. We also study fundamental frequencies of in the vertical and radial oscillations of charged particles around circular stable orbits around the magnetized black hole. The effects of the magnetic interaction and length parameters on the fundamental frequencies. We investigate the quasiperiodic oscillations (QPOs) around the black hole in relativistic precession and epicyclic resonance models. It is also shown that the combined effects of magnetic interaction for negatively charged particles and length parameters can mimic the spacetime effects of the Schwarzschild black hole compensating for their effects, as well as the spin of rotating Kerr black holes. The distance between an orbit where a QPO is generated with the ratio of upper and lower frequencies 3: 2 and innermost stable circular orbits is also studied. It is found that the QPO orbits are very close to ISCO in the RP model at l &lt; 2. This implies that the obtained result helps to determine the ISCO around black holes. We also study the applications of observed-QPOs around stellar-mass black holes in microquasars and supermassive black holes.
