Hydrogen and helium are the most abundant elements in the Universe. They are also, in
principle, the most simple. Nonetheless, they display remarkable properties under extreme …

The giant planets were the first to form and hold the key to unveiling the solar system's
formation history in their interiors and atmospheres. Furthermore, the unique conditions …

We present new equations of state (EOSs) for hydrogen and helium covering a wide range
of temperatures from 60 K to 10 7 K and densities from 10− 10 g cm− 3 to 10 3 g cm− 3. They …

Two variants of optical imaging velocimetry, specifically the one-dimensional streaked line-
imaging and the two-dimensional time-resolved area-imaging versions of the Velocity …

Laser-driven shock wave measurements on hydrogen and deuterium precompressed in
diamond anvil cells from 0.16 to 1.6 GPa provide new shock Hugoniot data over a …

Giant planets acquire gas, ices and rocks during the early formation stages of planetary
systems and thus inform us on the formation process itself. Proceeding from inside out …

We review the interior structure and evolution of Jupiter, Saturn, Uranus and Neptune, and
giant exoplanets with particular emphasis on constraining their global composition …

Brillouin scattering spectroscopy has been used to obtain an accurate (< 1%) ρ-P equation
of state (EOS) of 1: 1 and 9: 1 H 2-He molar mixtures from 0.5 to 5.4 GPa at 296 K. Our …

Accurate knowledge of the properties of hydrogen at high compression is crucial for
astrophysics (eg, planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) …
