Magnetic investigations for studying planetary interiors
Annals of Geophysics, 1994 Most of the magnetic methods used for investigating planetary interiors are based on the reasonable hypothesis that the mechanism for the origin of the field is an Earth-like hydromagnetic dynamo: in this case the planet has an electrically conducting ...

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

Magnesium oxide-water compounds at megabar pressure and implications on planetary interiors [PDF]
Nature Communications, 2023 Magnesium Oxide and water are abundant in the interior of planets. Here, the authors predict three new MgO-H2O compounds: Mg2O3H2, MgO3H4 and MgO4H6, and they exhibit superionic behavior in planetary interior conditions.

Hydrogen-helium immiscibility boundary in gas-giant planetary interiors from machine-learning molecular dynamics [PDF]
Nature CommunicationsThe location of the hydrogen-helium (H/He) immiscibility boundary controls whether and where helium rain occurs in giant planets, yet it remains uncertain because high-pressure experiments are challenging and ab initio simulations are limited in system ...

Seven decades of exploring planetary interiors with rotating convection experiments [PDF]
Comptes Rendus. PhysiqueThe interiors of all the planets in the solar system consist of layers, most of which are made out of fluids. When these layers are subject to superadiabatic temperature or compositional gradients, turbulent convection takes place that transports heat ...

Shock compression of FeOOH and implications for iron-water interactions in super-earth magma oceans [PDF]
Nature CommunicationsIron(Fe)-water reactions in a magma ocean can influence water storage and density of planets. These reactions can form Fe-O-H phases, whose density, melting, and electronic properties at planetary interior conditions are important for informing planetary
