Orbital precession and other properties of two-body motion in the presence of dark energy
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.
