Evolution of Lunar Orbit under Climate Dynamics since the Last Glacial Cycle

open access: yesThe Astrophysical Journal
Understanding the long-term evolution of lunar orbit is an essential task in astronomy and astrophysics because lunar and planetary ephemerides are indispensable in many important applications, such as spacecraft navigation and reference frame ...

A semi-analytical method of computation of oceanic tidal perturbations in the motion of artificial satellites [PDF]

open access: yes
The method of expansion of the satellite's perturbations, as caused by the oceanic tides, into Fourier series is discussed. The coefficients of the expansion are purely numerical and peculiar to each particular satellite.

Kepler Multitransiting System Physical Properties and Impact Parameter Variations

open access: yesThe Astronomical Journal
We fit a dynamical model to Kepler systems that contain four or more transiting planets using the analytic method AnalyticLC and obtain physical and orbital parameters for 101 planets in 23 systems, of which 95 are of mass significance better than 3 σ ...
