Multiple Waves and the Lunar Core

摘要

The model of the internal structure of the Moon with "open" deep faults and weak contacts between sides for many lunar regions explains the existence of a block structure [1-3]. A high seismic Q-factor of lunar structures and significant impact energy (～ 10~(19) erg) produced by the fall of a large meteorite led to formation of multiple waves on the major internal lunar boundaries. The known statistical methods have allowed us to determine the vibration periods for these waves and, hence, to define the internal lunar structure, including the central zone (core).
