论文摘要
在涉及宇宙常数$λ$的弱场一般相对性的限制背景下，考虑了轨道晶状体的进动。结果表明，根据卫星测量的当前准确性，$λ$获得的误差限制与宇宙学观察值是自一成一的。 $λ$项的校正是针对强场晶状体 - 刺激性进进得出的，即框架拖动效果和螺母。结果，在最近提议的$λ$ - 重力的背景下，我们在相对论和弱场限制中都获得了$λ$的约束。也就是说，对于后者，我们在不同尺度上分析了几个开普勒系统。我们发现，所获得的修饰重力校正的限制比在太阳系中的重力红移，重力时间延迟和大地测量进液等效果相比，可用的几个数量级要高几个数量级。
The orbital Lense-Thirring precession is considered in the context of constraints for weak-field General Relativity involving the cosmological constant $Λ$. It is shown that according to the current accuracy of satellite measurements the obtained error limits for $Λ$ is self-consistent with cosmological observations. The corrections of $Λ$ term are derived for the strong field Lense-Thirring precession i.e. the frame dragging effect and for the nutation. As a result, in the context of recently proposed $Λ$-gravity we obtain constraints for $Λ$ in both relativistic and weak-field limits. Namely, for the latter we analyze several Keplerian systems at different scales. We find that the obtained constraints for the modified gravity corrections are several orders of magnitude tighter than those available for such effects as gravitational redshift, gravitational time delay and geodetic precession in Solar System.
