Orbital precession and other properties of two-body motion in the presence of dark energy
Gennady S. Bisnovatyi-Kogan, Marco Merafina
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…

Two body problem in presence of cosmological constant
G. S. Bisnovatyi-Kogan, M. Merafina
We consider the Kepler two-body problem in presence of the cosmological constant . Contrary to the classical case, where finite solutions exist for any angular momentum of the s…

A General Criterion for the Dynamical Stability of Anisotropic Newtonian Systems
Giuseppe Alberti, Marco Merafina
The problem of the dynamical stability of anistropic systems is studied, by proposing a criterion in terms of the adiabatic local index . The result has general validity and can…
