Circular motion around a rotating black hole in quintessential dark energy
2019
European Physical Journal C: Particles and Fields
This paper investigates the circular motion of neutral test particles orbiting near Kerr-Newman black hole in the presence of quintessential dark energy and cosmological constant. We limit our analysis to the equatorial plane and explore the properties of both time-like and null geodesics. The behavior of the specific energy and the angular momentum of the co-rotating as well as the counter rotating particles is analyzed. We also discuss the stable regions with respect to the horizons, radius
