Taking control of compressible modes: bulk viscosity and the turbulent dynamo
James R. Beattie, Christoph Federrath, Neco Kriel +2
Many polyatomic astrophysical plasmas are compressible and out of chemical and thermal equilibrium, introducing a bulk viscosity into the plasma via the internal degrees of freedom…
Numerical viscosity and resistivity in MHD turbulence simulations
Lakshmi Malvadi Shivakumar, Christoph Federrath
Accurate magnetohydrodynamical (MHD) turbulence simulations require understanding numerical dissipation. We quantify numerical viscosity and resistivity in subsonic (M=0.1) and sup…
Structure of iso-density sets in supersonic isothermal turbulence
Fabien Thiesset, Christoph Federrath
Context: The gas density structure of the cold molecular phase of the interstellar medium is the main controller of star formation. Aims: A theoretical framework is proposed to des…
Compressible turbulence in the interstellar medium: New insights from a high-resolution supersonic turbulence simulation
Renaud Ferrand, Sébastien Galtier, Fouad Sahraoui +1
The role of supersonic turbulence in structuring the interstellar medium (ISM) remains an unsettled question. Here, this problem is investigated using a newexact law of compressibl…
