Geodesic structure of a rotating regular black hole

Understand

We examine the dynamics of particles around a rotating regular black hole.

• In particular we focus on the effects of the characteristic length parameter of the spinning black hole on the motion of the particles by solving the equation of orbital motion.
• We have found that there is a fourth constant of motion that determines the dynamics of orbits out the equatorial plane similar as in the Kerr black hole.
• Through detailed analyses of the corresponding effective potentials for massive particles the possible orbits are numerically simulated.
