The influence of geometry and topology on axisymmetric mean-field dynamos
E. Covas, R. Tavakol, A. Tworkowski +3
We study the changes in the dynamical behaviour of axisymmetric spherical mean-field dynamo models produced by changes in their geometry and topology, by considering a two paramete…

Mean Field Dynamos with Algebraic and Dynamic alpha-Quenchings
A. Tworkowski, E. Covas, R. Tavakol +1
Calculations for mean field dynamo models (in both full spheres and spherical shells), with both algebraic and dynamic --quenchings, show qualitative as well as quantitative dif…
