Abstract

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.

暗能量存在下一对引力体的运动：与开普勒运动的微小偏差

摘要

研究了在存在暗能量（DE）的情况下两个重力物体的运动问题，该能量被认为是扰动因素。除了先前研究获得的轨道进动频率外，还计算了对轨道运动频率的校正，并研究了由DE的影响引起的半长轴振动和轨道偏心率。
