We develop a long-term 1-D evolution model for icy satellites that couples multiple processes: water migration and differentiation, geochemical reactions and silicate phase transitions, compaction by self-gravity, and ablation. The model further considers the following energy sources and sinks: tidal heating, radiogenic heating, geochemical energy released by serpentinization or absorbed by mineral...
We use a one-dimensional adaptive-grid thermal evolution code to model Kuiper belt objects Charon, Orcus and Salacia and compare their measured bulk densities with those resulting from evolutionary calculations at the end of 4.6Gyr. Our model assumes an initial homogeneous composition of mixed ice and rock, and follows the multiphase flow of water through the porous rocky medium, consequent differentiation...
Serpentinization is an exothermic reaction which involves the metamorphic transition of ultramafic rocks, and liquid water, into hydrated serpentine minerals. It has been suggested that serpentinization may be a fundamental process in the development of icy planetary objects, prompting a reaction runaway, in which heat from serpentinization in a localized region of the body could result, in principle,...
