Orbital precession and other properties of two-body motion in the presence of dark energy
arXiv:2409.11427 · doi:10.1142/S021827182350030X
Abstract
We consider the Kepler two-body problem in the presence of a cosmological constant Lambda. Several dimensionless parameters characterizing the possible orbit typologies are used to identify open and closed trajectories. The qualitative picture of the two-body motion is described and critical parameters of the problem are found.
