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…
Material Properties for the Interiors of Massive Giant Planets and Brown Dwarfs
Andreas Becker, Mandy Bethkenhagen, Clemens Kellermann +2
We present thermodynamic material and transport properties for the extreme conditions prevalent in the interiors of massive giant planets and brown dwarfs. They are obtained from e…
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…
Planetary Ices and the Linear Mixing Approximation
Mandy Bethkenhagen, Edmund R. Meyer, Sebastien Hamel +8
The validity of the widely used linear mixing approximation for the equations of state (EOS) of planetary ices is investigated at pressure-temperature conditions typical for the in…
Uranus evolution models with simple thermal boundary layers
N. Nettelmann, K. Wang, J. J. Fortney +4
The strikingly low luminosity of Uranus (Teff ~ Teq) constitutes a long-standing challenge to our understanding of Ice Giant planets. Here we present the first Uranus structure and…
