Reynolds stress and heat flux in spherical shell convection
P. J. Käpylä, M. J. Mantere, G. Guerrero +2
(abridged) Context. Turbulent fluxes of angular momentum and heat due to rotationally affected convection play a key role in determining differential rotation of stars. Here we per…
Can catastrophic quenching be alleviated by separating shear and alpha effect?
Piyali Chatterjee, Axel Brandenburg, Gustavo Guerrero
The small-scale magnetic helicity produced as a by-product of the large-scale dynamo is believed to play a major role in dynamo saturation. In a mean-field model the generation of…
Magnetic helicity fluxes in interface and flux transport dynamos
Piyali Chatterjee, Gustavo Guerrero, Axel Brandenburg
Dynamos in the Sun and other bodies tend to produce magnetic fields that possess magnetic helicity of opposite sign at large and small scales, respectively. The build-up of magneti…
Shear-driven and diffusive helicity fluxes in alpha-Omega dynamos
Gustavo Guerrero, Piyali Chatterjee, Axel Brandenburg
We present nonlinear mean-field alpha-Omega dynamo simulations in spherical geometry with simplified profiles of kinematic alpha effect and shear. We take magnetic helicity evoluti…
