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.

On the magnetic sounding of planetary interiors

Physics of the Earth and Planetary Interiors, 1996
Abstract Two ways have been suggested for using the magnetic field of a planet to estimate the radius of its electrically conducting core, assumed spherical and concentric with the planet's surface. In the frozen flux method, the core radius is assumed to have the value rFF for which the integrated unsigned radial magnetic flux, from the sphere of ...

Plasmas in Planetary Interiors

2005
We give an overview of the properties of matter in planetary interiors. Of special interest are the equation of state and the conductivities. This field has gained much more interest because of the detection of Jupiter-like, extrasolar planets since 1995.

Calculations on the evolution of the planetary interiors

Tectonophysics, 1977
Abstract Evolution of the internal structure of the terrestrial planets is considered with the aid of a model of gravitational differentiation of a spherically symmetrical and initially homogeneous solid planet composed of light “mantle” and heavy “core” materials. Fe 2 O was taken as the “core” material.

Convection in planetary interiors

Icarus, 1968
Abstract The aim of the present paper is to formulate explicitly the linearized equations safe-guarding the conservation of mass, energy, and momentum of viscous flow inside a heterogeneous, compressible, rotating fluid configuration, in which the coefficient of viscosity is an arbitrary function of radial distance, and the rotation is about a fixed

Magnetic probing of planetary interiors

Physics of the Earth and Planetary Interiors, 1979
Abstract The following general question is addressed: what can be learned about a planetary interior from measurements of the global planetary magnetic field at (or near) its surface? The discussion is placed in the context of Earth, for clarity, but the considerations apply to terrestrial planets in general (so long as the observed magnetism is ...

Aspects of the physics of planetary interiors

Contemporary Physics, 1981
Abstract Data from space missions of various kinds coupled with those from Earth-based observatories have allowed us to pass beyond the separate study of individual planets to the study of the Solar System as a composite physical system. We can identify those physical principles which are characteristic of planetary bodies over the full range of ...

Evidence on the deeper planetary interiors

Physics of the Earth and Planetary Interiors, 1972
Various theories are evaluated that have arisen in attempts at determining the physics of planetary interiors by observations from the gravitational field and radiation from the surface. It is concluded that there appears great scope in obtaining data from planetary fields which will provide not only evidence of static structure but also of dynamic ...
