Mean-field interpretation of star-in-a-box simulations of red giants

Carolina A. Ortiz-Rodríguez, Axel Brandenburg, Petri J. Käpylä

The paper uses mean‑field dynamo models, constrained by differential rotation profiles from global 3D simulations, to explain how magnetic fields are generated and evolve in red gi…

Magnetorotational instability in a solar near-surface mean-field dynamo

Axel Brandenburg, Gustav Larsson, Fabio Del Sordo +1

We address the question whether the magnetorotational instability (MRI) can operate in the near-surface shear layer (NSSL) of the Sun and how it affects the interaction with the dy…

Magnetic field amplification during a turbulent collapse

Axel Brandenburg, Evangelia Ntormousi

The question of whether a dynamo can be triggered by gravitational collapse is of great interest, especially for the early Universe. Here, we employ supercomoving coordinates to st…

Magnetic helicity fluxes in dynamos from rotating inhomogeneous turbulence

Axel Brandenburg, Ethan T. Vishniac

We analyze direct numerical simulations of large-scale dynamos in inhomogeneous nonhelically driven rotating turbulence with and without shear. The forcing is modulated so that the…

Spectra of magnetic fields from electroweak symmetry breaking

Tanmay Vachaspati, Axel Brandenburg

We characterize magnetic fields produced during electroweak symmetry breaking by non-dynamical numerical simulations based on the Kibble mechanism. The generated magnetic fields we…

Inverse cascade from helical and nonhelical decaying columnar magnetic fields

Axel Brandenburg, Longqing Yi, Xianshu Wu

Powerful lasers may in future produce magnetic fields that would allow us to study turbulent magnetohydrodynamic inverse cascade behavior. This has so far only been seen in numeric…
