Non-normal parameter blowout bifurcation: an example in a truncated mean field dynamo model
Eurico Covas, Peter Ashwin, Reza Tavakol
We examine global dynamics and bifurcations occurring in a truncated model of a stellar mean field dynamo. This model has symmetry-forced invariant subspaces for the dynamics and w…
Axisymmetric mean field dynamos with dynamic and algebraic --quenchings
Eurico Covas, Reza Tavakol, Andrew Tworkowski +1
We study axisymmetric mean field spherical and spherical shell dynamo models, with both dynamic and algebraic --quenchings. Our results show that there are qualitative as well a…
Crisis-induced intermittency in truncated mean field dynamos
Eurico Covas, Reza Tavakol
We investigate the detailed dynamics of a truncated dynamo model with a dynamic effect. We find the presence of multiple attractors, including two chaotic attractors with…
Robustness of truncated alpha-Omega dynamos with a dynamic alpha
Eurico Covas, Andrew Tworkowski, Reza Tavakol +1
In a recent work (Covas et al. 1997), the behaviour and the robustness of truncated dynamos with a dynamic were studied with respect to a number of changes in the driving…
Dynamos with different formulations of a dynamic alpha-effect
Eurico Covas, Andrew Tworkowski, Axel Brandenburg +1
We investigate the behaviour of dynamos with a dynamic , whose evolution is governed by the imbalance between a driving and a damping term. We focus on truncated versions o…
