Origin of the moon. New concept. Geochemistry and dynamics. (Q2919649)

The two parts of this book are headed as ``Geochemistry'' and ``Dynamics''. The first part considers the Moon as geological body and compares its composition with that of the Earth. The second part deals with the several theories how the Earth-Moon system might have been evolved. There the dynamics of the preplanetary processes play a crucial role. The present authors concentrate their research on the giant impact hypothesis, i.e., the formation of the Moon as a result of a collision of the Earth with a planet-sized body. To this end they developed a number of computational models.NEWLINENEWLINEHere is the publisher's description: ``The origin of the Moon remains an unsolved problem of the planetary science. Researchers engaged in celestial dynamics, geophysics, and geochemistry are still discussing various models of creation of our closest cosmic neighbour. The most popular scenario, the impact hypothesis involving a collision early in the Earth's history, has been substantially challenged by the new data. The birth and development of a planet-moon system always plays a role in the formation of an entire planetary system around our Sun or around another star. This way, the story of our Moon acquires broader ramifications for one of the hottest topics of the modern scholarship. All this has motivated the authors of this book to consider a new concept and to compare the currently discussed theories, analyzing their advantages and shortcomings in explaining the experimental data.''
