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…
Fundamental MHD scales -- II: the kinematic phase of the supersonic small-scale dynamo
Neco Kriel, James R. Beattie, Christoph Federrath +2
Many astrophysical small-scale dynamos (SSDs) amplify weak magnetic fields via highly compressible, supersonic turbulence, but established SSD theories have overlooked these compre…
Growth or Decay -- I: universality of the turbulent dynamo saturation
James R. Beattie, Christoph Federrath, Neco Kriel +2
The turbulent small-scale dynamo (SSD) is likely to be responsible for the magnetisation of the interstellar medium (ISM) that we observe in the Universe today. The SSD efficiently…
Energy balance and Alfvén Mach numbers in compressible magnetohydrodynamic turbulence with a large-scale magnetic field
James R. Beattie, Mark R. Krumholz, Raphael Skalidis +5
Energy equipartition is a powerful theoretical tool for understanding astrophysical plasmas. It is invoked, for example, to measure magnetic fields in the interstellar medium (ISM)…
