Stratified rheological models for icy worlds with liquid layers

Abstract

The goal of this project is to propose and analyse multilayered rheological models for the dynamics of icy satellites with subsurface oceans evolving under the influence of gravitational forces. Important questions that we intend to address with the proposed models are, among others, (i)~whether the tidal dissipation in the liquid layer caused by the forced librations and the obliquity of the orbit of the satellites is large enough compared with the dissipation in the solid layers and the radiogenic heating and (ii)~to explore the limits of applicability of effective rheological models to stratified icy satellites.
