  author={Dmitry G. Kiryan and George V. Kiryan},
In this work, the nutation momentum acting upon the Earth from the Moon's perigee mass that has not been taken into account in the Earth's precession‐nutation theory was revealed. This missing momentum exhibits itself in the so‐called “local latitude variation” with the Chandler's period. The results of our work raise the question of updating the Earth's precession‐nutation theory and revising some postulates of the time service, astronomy, geophysics, satellite navigation, etc. (© 2014 Wiley…

The problem of the two‐body gravitational interaction has been solved numerically based on the classical mechanics principles. One of the bodies is a deformable three‐axis ellipsoid (central body)

The Evolution of the System of Gravitating Bodies

A natural physical approach to the analysis of the structure of closed gravitating systems has been formulated in the scope of classical mechanics. The approach relies on the interrelation between

Gravitational Interaction in the Medium of Non-Zero Density

The paper presents the novel results obtained by more comprehensively analyzing well-known and clearly visible physical processes associated with gravitational interaction in the system of material



The Chandler wobble is a phantom

  • Physics, Geology
  • 2012
In this paper we have proved that the assertion on the existence of residual motion of the Earth rotation axis within the Earth is a result of erroneous interpretation of the zenith distance (angle)

The Chandler wobble is an excited resonance of the Earth's rotation having a period of about 14 months. Although it has been under investigation for more than a century, its excitation mechanism has

Two years of continuous measurements of tidal and nontidal variations of gravity in Boulder, Colorado

We report here on the results of an analysis of 2 years of data from NOAA's superconducting gravimeter located at the Table Mountain Gravity Observatory in Boulder, Colorado. Observed tidal

How to detect the Chandler and the annual wobble of the Earth with a large ring laser gyroscope.

A 16 m(2) helium-neon ring laser gyroscope with sufficient sensitivity and stability to directly detect the Chandler wobble of the rotating Earth is demonstrated.

Invited review article: Large ring lasers for rotation sensing.

The first experimentally viable proposals to make terrestrial tests of general relativistic effects such as the frame dragging of the rotating Earth are proposed.
