Tidal constraints on the low-viscosity zone of the Moon

In this paper, the effect on tidal response of low-viscosity zone in deep interior Moon is investigated based hypothetical temperature profiles. The parameters are computed numerically to demonstrate their dependence and frequency. One calculated quality factor, which energy dissipation inversely proportional. other Love numbers, normalized magnitudes displacement potential perturbation deformation. Unlike earlier considerations, viscosity structure no longer assumed be fully uniform but linked with several profiles such as a thermal boundary layer model or convective model. calculations show that latest observational ranges frequency-dependent factors can satisfied only by some value for middle not any structure. approximate solution estimated 3 × 1016 Pa s. If considering also numbers together those factors, outer radius approximately either 560 580 km. These solutions almost identical previous where has viscosity. It concluded state bottom lunar mantle predicted mainly controlled local convection, possibly maintained balance between cooling heating, previously suggested.
