VARIATIONAL PRINCIPLE FOR PLANETARY INTERIORS [PDF]
The Astrophysical Journal, 2016 ABSTRACT In the past few years, the number of confirmed planets has grown above 2000. It is clear that they represent a diversity of structures not seen in our own solar system. In addition to very detailed interior modeling, it is valuable to have a simple analytical framework for describing planetary structures.

Fluid Dynamics Experiments for Planetary Interiors [PDF]
Surveys in Geophysics, 2021 AbstractUnderstanding fluid flows in planetary cores and subsurface oceans, as well as their signatures in available observational data (gravity, magnetism, rotation, etc.), is a tremendous interdisciplinary challenge. In particular, it requires understanding the fundamental fluid dynamics involving turbulence and rotation at typical scales well beyond

Eos, Transactions American Geophysical Union, 1985 The effective definition of a planet is a body too small to sustain nuclear reactions in its interior, but large enough that its thermal decay time is more than five billion years, the age of the solar system. By this definition, there are fifteen planets in the solar system: all the conventional planets but Pluto plus the seven large satellites.

Probing the Rock Mass Fraction and Transport Efficiency inside Uranus Using 40Ar Measurements
The Planetary Science JournalThe bulk of Uranus consists of a rock–ice core, but the relative proportions of rock and ice are unknown. Radioactive decay of potassium in the silicates produces ^40 Ar.
