Stability of Planetary Interiors

Geophysical Journal International, 1969
Summary Many accept thermal convection within the mantle of the Earth as the driving mechanism for continental drift. It is also of considerable interest to determine whether thermal convection is occurring within Venus, Mars, and the Moon. In this paper a systematic treatment of the stability of planetary interiors is given.

Interior Structure, Planetary

2011
Models of the interior structure of a ▶ planet or ▶ satellite give the variations of thermodynamic state variables as functions of radius (starting at the center) or depth (starting at the surface). The thermodynamic state variables are pressure, temperature, density (or specific volume), and the concentration of chemical species.

The Rheology of the Planetary Interior

Journal of Rheology, 1984
The mantle of the earth is rheologically similar to an amorphous polymer. The short‐time‐scale behavior in shear is anelastic and rather well described by a constant Q absorption band. The long‐time‐scale behavior is essentially Newtonian viscous and this mode of deformation dominates the material behavior for times in excess of a Maxwell time which is

Compressibility and planetary interiors

Physics of the Earth and Planetary Interiors, 1972
Important confirmations that the Earth's inner core is solid have recently come from analyses of records of free Earth oscillations and from the apparent detection of the seismic phase PKJKP. Corresponding support is given to the theory which supplied the primary evidence for rigidity in the inner core.

Planetary seismology and interiors

Reviews of Geophysics, 1979
The placing of the first seismometer on the Moon by the Apollo 11 astronauts in 1969 started the field of planetary seismology. In the following years five other seismic stations were established on the Moon. The seismic network was operated continuously until all of the ALSEP stations were turned off on 1 October 1977.
