A new simple dynamo model for stellar activity cycle
Nobumitsu Yokoi, Dieter Schmitt, Valery Pipin +1
A new simple dynamo model for stellar activity cycle is proposed. By considering an inhomogeneous mean flow effect on turbulence, it is shown that turbulent cross helicity (velocit…
Hemispherical Parker waves driven by thermal shear in planetary dynamos
Wieland Dietrich, Dieter Schmitt, Johannes Wicht
Planetary and stellar magnetic fields are thought to be sustained by helical motions (-effect) and, if present, differential rotation (-effect). In the Sun, the strong differ…
Limits to solar cycle predictability: Cross-equatorial flux plumes
R. H. Cameron, M. Dasi-Espuig, J. Jiang +3
Within the Babcock-Leighton framework for the solar dynamo, the strength of a cycle is expected to depend on the strength of the dipole moment or net hemispheric flux during the pr…
Modeling Solar Cycles 15 to 21 Using a Flux Transport Dynamo
J. Jiang, R. H. Cameron, D. Schmitt +1
Context: The Sun's polar fields and open flux around the time of activity minima have been considered to be strongly correlated with the strength of the subsequent maximum of solar…
Modelling stellar activity cycles using deep-seated dynamos and surface flux transport
Emre Işik, Dieter Schmitt, Manfred Schüssler
We investigate the relations between tachocline-based dynamos and the surface flux transport mechanisms in stars with outer convection zones. Using our combined models of flux gene…
Surface flux evolution constraints for flux transport dynamos
R. H. Cameron, D. Schmitt, J. Jiang +1
The surface flux transport (SFT) model of solar magnetic fields involves empirically well-constrained velocity and magnetic fields. The basic evolution of the Sun's large-scale sur…
