  • Astrophysically relevant bound trajectories around a Kerr black hole 
    Prerna Rana; Mangalam, A (IOP Publishing, 2019-02-21)
    We derive alternate and new closed-form analytic solutions for the nonequatorial eccentric bound trajectories, {φ (r, θ), t(r, θ), r(θ)}, around a Kerr black hole by using the transformation 1/r = µ (1 + e cos χ). The ...
  • Bound orbit domains in the phase space of the Kerr geometry 
    Prerna Rana; Mangalam, A (World Scientific Publishing, 2022)
    We derive the conditions for a non-equatorial eccentric bound orbit to exist around a Kerrblack hole in two-parameter spaces: the energy, angular momentum of the test particle,spin of the black hole, and Carter’s constant ...
  • Eccentric equatorial trajectories around a Kerr black hole asa QPO model for M82X-1 
    Prerna Rana; Mangalam, A (World Scientific Publishing, 2022)
    We study the bound orbit conditions for equatorial and eccentric orbits around a Kerrblack hole both in the parameter space (E,L,a) representing the energy, angular mo-mentum of the test particle, and spin of the black ...
