Spin crossover in FeO under shock compression

Lélia Libon, Alessandra Ravasio, Silvia Pandolfi +17

FeO (wüstite), which exhibits complex electronic and structural properties with increasing pressure and temperature, is a key mineralogical phase for understanding deep planetary i…

Shock-driven amorphization and melt in FeO

Céline Crépisson, Alexis Amouretti, Marion Harmand +28

We present measurements on FeO amorphization and melt under laser-driven shock compression up to 209(10) GPa via time-resolved in situ x-ray diffraction. At 122(3) GPa, a d…

Laser-driven shock compression and equation of state of FeO up to 700 GPa

Alexis Amouretti, Marion Harmand, Bruno Albertazzi +7

We report here the first equation of state measurements of FeO obtained with laser-driven shock compression. The data are in excellent agreement with previous dynamic and s…

Metallization of Shock-Compressed Liquid Ammonia

A. Ravasio, M. Bethkenhagen, J. -A. Hernandez +8

Ammonia is predicted to be one of the major components in the depths of the ice giant planets Uranus and Neptune. Their dynamics, evolution, and interior structure are insufficient…

Characterising equation of state and optical properties of dynamically pre-compressed materials

M. Guarguaglini, J. -A. Hernandez, A. Benuzzi-Mounaix +4

Characterising materials at pressures of several megabar and temperatures of a few thousand Kelvin is critical for the understanding of the Warm Dense Matter regime and to improve…

Equation of state and optical properties of shock-compressed C:H:N:O molecular mixtures

M. Guarguaglini, J. -A. Hernandez, T. Okuchi +14

Water, ethanol, and ammonia are the key components of the mantles of Uranus and Neptune. To improve structure and evolution models and give an explanation of the magnetic fields an…

Decaying shock studies of phase transitions in MgOSiO2 systems: implications for the Super-Earths interiors

R. M. Bolis, G. Morard, T. Vinci +15

We report an experimental study of the phase diagrams of periclase (MgO), enstatite (MgSiO3) and forsterite (Mg2SiO4) at high pressures. We investigated with laser driven decaying…

Melting of iron close to Earth's inner core boundary conditions and beyond

M. Harmand, A. Ravasio, S. Mazevet +23

Several important geophysical features such as heat flux at the Core-Mantle Boundary or geodynamo production are intimately related with the temperature profile in the Earth's core…

Melting and metallization of silica in the cores of gas giants, ice giants and super Earths

S. Mazevet, T. Tsuchiya, T. Taniuchi +2

The physical state and properties of silicates at conditions encountered in the cores of gas giants, ice giants and of Earth like exoplanets now discovered with masses up to severa…

Experimental demonstration of an inertial collimation mechanism in nested outflows

R. Yurchak, A. Ravasio, A. Pelka +10

Interaction between a central outflow and a surrounding wind is common in astrophysical sources powered by accretion. Understanding how the interaction might help to collimate the…
