Internal Structure of Enceladus and Dione from Orbital Constraints
Introduction Enceladus is emitting measurable heat (37 GW) from a region centered on its South Pole [1]. Radioactive and accretional heating are expected to be minimal for such a small, low-density body, implying that the observed heat flow is due to past or present tidal dissipation [2]. The tidal heat production for which Enceladus’ eccentricity is in steady state, however, cannot exceed 1.1 ...
متن کاملGeophysical inversion using petrophysical constraints
Petrophysical information is sometimes available from well logs, laboratory measurements, etc. It has been shown that incorporation of such information into geophysical inversions can greatly improve the recovered models. However, when the known petrophysical information is not applicable throughout the entire region, the application of petrophysical constraints to geophysical inversions could ...
متن کاملGeophysical and geochemical constraints on geoneutrino fluxes from Earth's mantle
Knowledge of the amount and distribution of radiogenic heating in the mantle is crucial for understanding the dynamics of the Earth, including its thermal evolution, the style and planform of mantle convection, and the energetics of the core. Although the flux of heat from the surface of the planet is robustly estimated, the contributions of radiogenic heating and secular cooling remain poorly ...

متن کاملCore cracking and hydrothermal circulation can profoundly affect Ceres' geophysical evolution
Observations and models of Ceres suggest that its evolution was shaped by interactions between liquid water and silicate rock. Hydrothermal processes in a heated core require both fractured rock and liquid. Using a new core cracking model coupled to a thermal evolution code, we find volumes of fractured rock always large enough for significant interaction to occur. Therefore, liquid persistence...
