Motion of a pair of gravitating bodies in dark energy presence: small deviations from Keplerian motion

journal contribution
posted on 18.08.2020, 09:27 by Anatoly Neishtadt, Gennady Bisnovatyi-Kogan
The problem of the motion of two gravitating bodies in the presence of dark energy (DE), considered as a perturbing factor, is investigated. In addition to the orbit precession frequency obtained in previous studies, the correction to the orbital motion frequency was calculated, and the oscillations of the semi-major axis and the eccentricity of the orbit caused by the influence of DE were studied.
