1206.0306 (Yurii V. Dumin)

Lambda-Perturbations of Keplerian Orbits    [PDF]

Yurii V. Dumin
To estimate the influence of the dark energy on the planetary orbits, we solve the general relativistic equations of motion of a test particle in the field of a point-like mass embedded in the cosmological background formed by the Lambda-term. It is found that under certain relations between three crucial parameters of the problem--the initial radius of the orbit, Schwarzschild and de Sitter radii--a secular perturbation caused by the Lambda-term becomes significant, i.e. can reach the rate of the standard Hubble flow.
