Scaling properties of convection-driven dynamos in rotating spherical shells and application to planetary magnetic fields

We study numerically an extensive set of dynamo models in rotating spherical shells, varying all relevant control parameters by at least two orders of magnitude. Convection is driven by a fixed temperature contrast between rigid boundaries. There are two distinct classes of solutions with strong and...
