Magnetic Dynamo Driven by Inertial Waves
A. Mishra, G. Mamatsashvili, M. Le Bars +2
We demonstrate, by studying precession-driven flows, that inertial wave hydrodynamic turbulence can drive a robust magnetic dynamo action. Motivated by the stronger damping of larg…

Tidal triggers and the predictability of solar activity
F. Stefani, G. M. Horstmann, G. Mamatsashvili +1
Magneto-Rossby waves in the solar tachocline are currently considered to be one of the main determinants of solar activity. In particular, they can give rise to the quasi-biennial…

Strong and weak dynamo regimes in Taylor-Couette flows
A. Mishra, G. Mamatsashvili, F. Stefani
We reveal a nonlinear magnetic dynamo in a Taylor-Couette flow at small magnetic Prandtl numbers , which has been previously believed to exist only at higher $Pm\gtrsim 1…
