Astrophysical turbulence modeling
Axel Brandenburg, Aake Nordlund
The role of turbulence in various astrophysical settings is reviewed. Among the differences to laboratory and atmospheric turbulence we highlight the ubiquitous presence of magneti…
Equatorial magnetic helicity flux in simulations with different gauges
Dhrubaditya Mitra, Simon Candelaresi, Piyali Chatterjee +2
We use direct numerical simulations of forced MHD turbulence with a forcing function that produces two different signs of kinetic helicity in the upper and lower parts of the domai…
Large-scale magnetic flux concentrations from turbulent stresses
Axel Brandenburg, Nathan Kleeorin, Igor Rogachevskii
In this study we provide the first numerical demonstration of the effects of turbulence on the mean Lorentz force and the resulting formation of large-scale magnetic structures. Us…
Magnetic field decay of three interlocked flux rings with zero linking number
Fabio Del Sordo, Simon Candelaresi, Axel Brandenburg
The resistive decay of chains of three interlocked magnetic flux rings is considered. Depending on the relative orientation of the magnetic field in the three rings, the late-time…
Turbulent diffusion and galactic magnetism
Axel Brandenburg, Fabio Del Sordo
Using the test-field method for nearly irrotational turbulence driven by spherical expansion waves it is shown that the turbulent magnetic diffusivity increases with magnetic Reyno…
The critical role of magnetic helicity in astrophysical large-scale dynamos
Axel Brandenburg
The role of magnetic helicity in astrophysical large-scale dynamos is reviewed and compared with cases where there is no energy supply and an initial magnetic field can only decay.…
