Saturation mechanism of the fluctuation dynamo in supersonic turbulent plasmas
Amit Seta, Christoph Federrath
Abstract
The physical mechanism of converting the kinetic energy of turbulence to magnetic energy is known as a dynamo. Fluctuation dynamo amplifies magnetic fields at scales smaller than the driving scale of turbulence. We show that the fluctuation dynamo in subsonic turbulent plasma is similar to the supersonic case in some aspects and very different in others.
