Galactic renormalization of gravitational potential of the Sun and Kimura's z-term.

Institute of Planetary Geophysics, RAS. Moscow, Russia

There are uncertainties in existing explanations for annual and half-annual terms in the spectrum of variations of the Earth revolution by tidal and/or meteorological factors. We propose to explain deficient values by an anisotropy of the correction factor in renormalized gravitational potential of the Sun.

The theory of renormalized potential of the Sun has been developed in [1-4] taking account for influence of a solar neighbour star population. For the simplest case of a homogeneous maxwellian system of gravitating bodies this potential can be represented as

As solar neighbouring is anisotropic the above values are anisotropic also, that results to additional annual and half-annual variations in the Earth revolution due to motion of the Sun toward an apex and orientation of the ecliptic plane relative to the Galaxy plane.
