A MODIFICATION OF GAUSS' METHOD FOR PRELIMINARY DETERMINATION OF A CELESTIAL BODY'S ORBIT

Odessa Astronomical Publications, 2016
A modification of classical Gauss’ method for determination of Keplerian elements from the observed positions is considered in this paper. The modification involves the exhaustive enumeration of all possible orbital plane positions in order to improve ...

15:1 Resonance effects on the orbital motion of artificial satellites [PDF]

Journal of Aerospace Technology and Management, 2011
The motion of an artificial satellite is studied considering geopotential perturbations and resonances between the frequencies of the mean orbital motion and the Earth rotational motion.

New Model for Hill’s Problem in the Framework of Continuation Fractional Potential

Mathematical and Computational Applications
In this work, we derived a new type model for spatial Hill’s system considering the created perturbation by the parameter effect of the continuation fractional potential. The new model is considered a reduced system from the restricted three-body problem

Dynamical Structures under Nonrestricted Hierarchical Planetary Systems with Different Mass Ratios

The Astronomical Journal
Secular dynamics have been extensively studied in both the inner and outer restricted hierarchical three-body systems. In the inner restricted problem, the quadrupole-order resonance (i.e., the well-known Kozai resonance) causes large coupled ...

Kepler Multitransiting System Physical Properties and Impact Parameter Variations

The 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 ...

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

The 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 ...
