Dynamo action driven by precessional turbulence
V. Kumar, F. Pizzi, G. Mamatsashvili +3
We reveal and analyze an efficient magnetic dynamo action due to precession-driven hydrodynamic turbulence in the local model of a precessional flow, focusing on the kinematic stag…
MRI turbulence in vertically stratified accretion discs at large magnetic Prandtl numbers
Loren E. Held, George Mamatsashvili, Martin E. Pessah
The discovery of the first binary neutron star merger, GW170817, has spawned a plethora of global numerical relativity simulations. These simulations are often ideal (with dissipat…
Rieger, Schwabe, Suess-de Vries: The Sunny Beats of Resonance
F. Stefani, G. M. Horstmann, M. Klevs +2
We propose a self-consistent explanation of Rieger-type periodicities, the Schwabe cycle, and the Suess-de Vries cycle of the solar dynamo in terms of resonances of various wave ph…
Non-axisymmetric modes of magnetorotational and possible hydrodynamical instabilities in the upcoming DRESDYN-MRI experiments -- linear and nonlinear dynamics
A. Mishra, G. Mamatsashvili, F. Stefani
The quest for an unambiguous detection of magnetorotational instability (MRI) in experiments is still ongoing despite recent promising results. To conclusively identify MRI in the…
Alfvén wave experiments with liquid rubidium in a pulsed magnetic field
Th. Gundrum, J. Forbriger, Th. Herrmannsdörfer +4
Magnetic fields are key ingredients for heating the solar corona to temperatures of several million Kelvin. A particularly important region with respect to this is the so-called ma…
