Аннотация: Unified theory of planetary processes of planets, satellites and the Sun Yuri Barkin Sternberg Astronomical Institute at Moscow State University, Moscow, Russia barkin@inbox.ru The key issue of the theory of natural planetary processes on the Earth and other celestial bodies, is the question about the sources of endogenous activity and the underlying mechanism of energetic excitation of celestial bodies. We offer a solution to this difficult question on the basis of the mechanism of excitation of the shells of a celestial body by gravitational attraction of the external celestial bodies. The main provision of the developed geodynamic concept lies in the fact that the planets, moons and the sun are the define system of shells (of the core, the mantle, and others), which make to each other a translational-rotational motion and deformation changes under the influence of others external celestial bodies (Barkin, 2002). We have developed the fundamentals of this geodynamic model of the forced and free oscillations of the shells. In particular, the tides in the visco-elastic mantle of the planet, which are generated by the gravitational forces of interaction with the movable core. They change over time leads to the dissipation of the mechanical energy in the material of planet, which is transformed into heat and generates the temperature field inside the planet. As a model of the undeformed planet e consider viscoelastic homogeneous sphere, the material behavior is described by the Kelvin - Voigt model. It is determined by the strain rate tensor of deformations of rotating planet and the average temperature field inside the planet. The integral heat flow as global so in the northern and southern hemispheres jf the Earth are deterined. The most important question, of course, at all times in the history of geosciences was the question about the source of energy (Khain, Lomize, 2005), which provides unprecedented activity of the Earth, and it is now known that many other celestial bodies. The known energy mechanisms such as radiogenic heat, tidal friction and others can not explain either by a total energy or cyclical processes, not to mention the above fine planetary phenomena of inversion, step-by-step phenomena, the activity of the polar regions and others (Barkin, 2002). The current research clearly shows that tidal friction gives only a small contribution to the total observed heat flow of the Earth (~ 0.4 TW) across the surface of the Earth, which is currently estimated at 46 ± 3 TW, i.e. order of one percent. The dissipation of tidal energy on Enceladus can explain only 1 part of 27 of the observed heat flow. The dissipation of tidal energy in the satellite Io explains only a small part of the observed heat flow and the endogenous activity of the satellite (Barkin, 2011). All these problems are solved with the help of the geodynamic mechanism of the forced relative oscillation of the core and mantle of the Earth (Barkin, 1999, 2002). These displacements of the core lead to a shift of the center of mass of the Earth relative to the mantle, which is currently available for the study of space geodetic techniques (satellite methods). Currently, revealed a wide range of oscillations of the center of mass of the Earth (Barkin et al., 2007; Gobinddass et al., 2009;) and discovered his secular trend towards the north (the area of the Taimyr Peninsula) (Barkin, 1995). On the other hand, the displacements of the center of mass of the Earth can restore the style and features of the relative displacements of the core and mantle of the Earth, to study geodynamic consequences of these shifts, such as deformation of the mantle, the variations of its elastic energy, power dissipation and heat flux of the planet, the other physical fields, the redistribution fluid masses and other studies carried out effectively solve the energy issue in the life of the planets and satellites. In particular the power of dissipation of the elastic energy of the mantle for the observed oscillations of the core and according to our estimates may be 1000 - 10,000 terawatt (TW). This is a huge value of power with a vengeance explains all the endogenous activity of the Earth. Regarded geodynamic model of the relative displacements and oscillations of the core and mantle explains all the fundamental properties of planetary processes on Earth and other planets, satellites and Sun: cyclicality, unity, synchronicity, inversion, polar activity, step-by-step phenomena, pilobraznost, orderliness, twisting of layers of the mantle, the pear-shaped, versatility. All the above phenomena and properties of endogenous activity of the celestial bodies are illustrated in report on the exaples of natural processes on Earth, the Sun, the Moon Enceladus, Titan, Mars, etc. References.
