Higher-order geodesic deviations and orbital precession in a Kerr-Newman space-time
arXiv:1906.00343 · doi:10.1007/s10714-019-2557-7
Abstract
A novel approximation method in studying the perihelion precession and planetary orbits in general relativity is to use geodesic deviation equations of first and high-orders, proposed by Kerner et.al. Using higher-order geodesic deviation approach, we generalize the calculation of orbital precession and the elliptical trajectory of neutral test particles to KerrNewman space-times. One of the advantage of this method is that, for small eccentricities, one obtains trajectories of planets without using Newtonian and post-Newtonian approximations for arbitrary values of quantity .
