Dynamo Scaling Relationships

  • Kyle Augustson (a1), Stéphane Mathis (a1), Sacha Brun (a1) and Juri Toomre (a2)

This paper provides a brief look at dynamo scaling relationships for the degree of equipartition between magnetic and kinetic energies. Two simple models are examined, where one that assumes magnetostrophy and another that includes the effects of inertia. These models are then compared to a suite of convective dynamo simulations of the convective core of a main-sequence B-type star and applied to its later evolutionary stages.
