Charged particle motion around a quasi-Kerr compact object immersed in an external magnetic field

Understand

We explore the electromagnetic fields around a quasi-Kerr compact object assuming it is immersed in an external asymptotically uniform magnetic field.

• Using the Wald method, components of the electromagnetic field in orthonormal basis have been obtained.
• We explore the charged particle motion around deformed Kerr compact objects in the presence of external asymptotically uniform magnetic fields.
• Using the Hamilton-Jacobi equation, we obtain the effective potential expression for the charged particle surrounding a quasi-Kerr compact object immersed in an external magnetic field.
