Metallization of fluid molecular hydrogen at 140 GPa (1.4 Mbar)
Electrical resistivities were measured for liquid H{sub 2} and D{sub 2} shock compressed to pressures of 93{endash}180 GPa (0.93{endash}1.8 Mbar). Calculated densities and temperatures were in theExpand

The equation of state of platinum to 660 GPa (6. 6 Mbar)
Platinum metal was shock compressed to 660 GPa using a two‐stage light‐gas gun to qualify this material as an ultrahigh‐pressure standard for both dynamic and static experiments. The shock velocityExpand

Metallization and Electrical Conductivity of Hydrogen in Jupiter
Electrical conductivities of molecular hydrogen in Jupiter were calculated by scaling electrical conductivities measured at shock pressures in the range of 10 to 180 gigapascals (0.1 to 1.8 megabars)Expand

Minimum metallic conductivity of fluid hydrogen at 140 GPa (1.4 Mbar)
Electrical conductivity measurements indicate that fluid hydrogen achieves the minimum conductivity of a metal at 140 GPa, ninefold initial liquid-H{sub 2} density, and 2600 K. Metallization densityExpand

Shock compression of aluminum, copper, and tantalum
Hugoniot curves for Al (alloy 11000), Cu (type oxygen‐free high‐conductivity), and Ta have been measured in the shock pressure range 30–430 GPa (0.3–4.3 Mbar) with a two‐stage light‐gas gun. ImpactorExpand

Chemical processes in the deep interior of Uranus.
The unusual magnetic fields of the planets Uranus and Neptune represent important observables for constraining and developing deep interior models. Models suggests that the unusual non-dipolar andExpand

Temperature measurements of shock-compressed liquid hydrogen: implications for the interior of Jupiter
Shock temperatures of hydrogen up to 5200 kelvin were measured optically at pressures up to 83 gigapascals (830 kilobars). At highest pressures, the measured temperatures are substantially lower thanExpand

Shock-induced martensitic transformation of highly oriented graphite to diamond
Shock‐wave profiles of highly ordered pyrolytic graphite shocked normal to the basal plane of the graphite crystal structure have been measured. For graphite with sufficient orientational order aExpand

Equation of state and electrical conductivity of water and ammonia shocked to the 100 GPa (1 Mbar) pressure range
Dynamic equation‐of‐state data for liquid H2O and NH3 were measured in the shock pressure range 30–230 GPa (0.3–2.3 Mbar) using a two‐stage light‐gas gun. Electrical conductivities of water were alsoExpand
