Tidal heating and convection in Io
[1] The prodigious heat flux emitted from the surface of Jupiter’s moon Io is produced in the interior of the satellite by viscoelastic dissipation of tidal energy and is generally thought to be brought to the surface by convective motions. New models of Io’s equilibrium thermal state are constructed using self-consistent calculations of tidal heating and convective heat transport. These models...
متن کاملEuropa: Tidal heating of upwelling thermal plumes and the origin of lenticulae and chaos melting
[1] Tidal heating models are linked to thermal convection models for ice having strongly temperature dependent viscosity. In the range of ice viscosity inferred from laboratory experiments, tidal forces will heat up rising diapirs on Europa. Partial melt produced in the rising diapirs is predicted to create disruption of near-surface materials and formation of lenticulae and chaos, even if the ...
متن کاملSpatial distribution of volcanoes on Io: Implications for tidal heating and magma ascent
Extreme volcanism on Io results from tidal heating, but its tidal dissipation mechanisms and magma ascent processes are poorly constrained. Here we analyze the distribution of volcanic hotspots and paterae identified within the first 1:15,000,000-scale global geologic map of Io to characterize their patterns of spatial organization. Ionian hotspots correspond to the locations of positive therma...
متن کاملTidal heating in Enceladus
The heating in Enceladus in an equilibrium resonant configuration with other saturnian satellites can be estimated independently of the physical properties of Enceladus. We find that equilibrium tidal heating cannot account for the heat that is observed to be coming from Enceladus. Equilibrium heating in possible past resonances likewise cannot explain prior resurfacing events. © 2007 Elsevier ...
متن کاملMelting of io by tidal dissipation.
The dissipation of tidal energy in Jupiter's satellite Io is likely to have melted a major fraction of the mass. Consequences of a largely molten interior may be evident in pictures of Io's surface returned by Voyager I.
