Platform for Probing Radiation Transport Properties of Hydrogen at Conditions Found in the Deep Interiors of Red Dwarfs
J. Lütgert, M. Bethkenhagen, B. Bachmann +19
We describe an experimental concept at the National Ignition Facility for specifically tailored spherical implosions to compress hydrogen to extreme densities (up to 800$\tim…
X-ray Thomson scattering spectra from DFT-MD simulations based on a modified Chihara formula
Maximilian Schörner, Mandy Bethkenhagen, Tilo Döppner +3
We study state-of-the-art approaches for calculating x-ray Thomson scattering spectra from density functional theory molecular dynamics (DFT-MD) simulations based on a modified Chi…
Virial Expansion of the Electrical Conductivity of Hydrogen Plasmas
Gerd Röpke, Maximilian Schörner, Ronald Redmer +1
The low-density limit of the electrical conductivity of hydrogen as the simplest ionic plasma is presented as function of temperature T and mass density n in form of a vir…
Ionization and transport in partially ionized multicomponent plasmas: Application to atmospheres of hot Jupiters
Sandeep Kumar, Anna Julia Poser, Manuel Schöttler +5
We study ionization and transport processes in partially ionized multicomponent plasmas. The plasma composition is calculated via a system of coupled mass action laws. The electron…
Carbon ionization at Gbar pressures: an ab initio perspective on astrophysical high-density plasmas
Mandy Bethkenhagen, Bastian B. L. Witte, Maximilian Schörner +6
A realistic description of partially-ionized matter in extreme thermodynamic states is critical to model the interior and evolution of the multiplicity of high-density astrophysica…
The structure in warm dense carbon
J. Vorberger, K. U. Plageman, R. Redmer
The structure of the fluid carbon phase in the pressure region of the graphite, diamond, and BC8 solid phase is investigated. We find increasing coordination numbers with an increa…
