Geodesic Structure of Test Particle in Bardeen Spacetime

Understand

The Bardeen model describes a regular space-time, i.e.

• a singularity-free black hole space-time.
• In this paper, by analyzing the behavior of the effective potential for the particles and photons, we investigate the time-like and null geodesic structures in the space-time of Bardeen model.
• At the same time, all kinds of orbits, which are allowed according to the energy level corresponding to the effective potentials, are numerically simulated in detail.
