Mean Field Dynamos with Algebraic and Dynamic [alpha]-Quenchings

Calculations for mean field dynamo models (in both full spheres and spherical shells), with both algebraic and dynamic α-quenchings, show qualitative as well as quantitative differences and similarities in the dynamical behaviour of these models. We summarise and enhance recent results with extra ex...

Summary:Calculations for mean field dynamo models (in both full spheres and spherical shells), with both algebraic and dynamic α-quenchings, show qualitative as well as quantitative differences and similarities in the dynamical behaviour of these models. We summarise and enhance recent results with extra examples. Overall, the effect of using a dynamic α appears to be complicated and is affected by the region of parameter space examined.
