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.

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

Convection in planetary interiors

Icarus, 1962
Die linearisierten Erhaltungssätze für Masse, Energie and Impuls werden für viskose Strömungen in einer heterogenen kompressiblen Flüssigkeitskugel abgeleitet. Dabei kann der Viskositätskoeffizient eine beliebige Funktion des Radius sein. Die Betrachtungen werden im Hinblick darauf angestellt, daß im durch radioaktive Zerfallswärme verflüssigten ...

Planetary Magnetic Fields: Planetary Interiors and Habitability

2016
Soon after its detection, radio emission from Jupiter was quickly identified as a product of its planetary-scale magnetic field. Subsequent spacecraft investigations have revealed that many of the planets—and even some moons—either currently have or have had in the past a planetaryscale magnetic field.

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 ...

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 ...
