Расщепление частоты свободной нутации ядра в магнитном поле Земли
Abstract
The analysis of last years measurements has shown that the accepted IAU2000 theory has the best characteristics in comparison with other nutation models. However the analysis of residual divergences of the theory and measurement has shown that the structure of these divergences does not correspond to predictions of IAU2000 nutation theory. According tothis predictions the quasi-systematic part of these divergences should represent its own fluctuations on frequency of the core free nutation. However, the correlation analysis reveals the greater number of harmonics. A model allowing to explain completely the presence of two main components in residual divergences of IAU2000 nutation theory and measurements is suggested. The received periods coincide with periodsalloted from residual divergences of IAU2000 model and the results of measurements.
