DYT2 - Frontiers in dynamo theory: from the Earth to the stars

The eleven year solar activity cycle is a remarkable example of regular behaviour emerging from an extremely turbulent system. The origin of this behaviour is a dynamo that involves the complicated interaction of rotation, turbulence and magnetic field. An outstanding problem of astrophysics and mathematical physics  is how to describe the statistics of systematic behaviour emerging from the underlying chaos, given that simulation of astrophysical objects is simply impossible. Here I shall introduce these fascinating dynamo phenomena and describe modern methods for tackling these interactions over vast ranges of spatial and temporal scales.
