Abstract:
The trajectories of nulllike and timelike geodesics for circular motion in the vicinity
of Reissner-Nordström (RN) black hole with Euler-Heisenberg (EH) parameter i.e; μ =
9.46691 × 10−6 are investigated and compared with RN case. We found that radius of
outer horizon is same for both cases, however, unlike the RN black hole which possesses
two horizons, EH case has only one horizon. We calculated energy, angular momentum and
effective potential. It was seen that effective potential is not affected by adding an extra
term with new parameter. The stability of circular orbits of particles is also discussed by
using the effective potential of the particles.
