Dynamo models and differential rotation in late-type rapidly rotating stars
E. Covas, D. Moss, R. Tavakol
Increasing evidence is becoming available about not only the surface differential rotation of rapidly rotating cool stars but, in a small number of cases, also about temporal varia…
The influence of density stratification and multiple nonlinearities on solar torsional oscillations
Eurico Covas, David Moss, Reza Tavakol
Analyses of recent helioseismic data have produced ample evidence for substantial dynamical variation of the differential rotation within the solar convection zone. Given the inevi…
Effects of boundary conditions on the dynamics of the solar convection zone
Reza Tavakol, Eurico Covas, David Moss +1
Recent analyses of the helioseismic data have produced evidence for a variety of interesting dynamical behaviour associated with torsional oscillations. What is not so far clear is…
Solar Cycle Variation of the Solar Internal Rotation: Helioseismic Inversion and Dynamo Modelling
S. Vorontsov, R. Tavakol, E. Covas +1
We report our first results on comparing the variations of the solar internal rotation with solar activity, as predicted by non-linear solar dynamo modelling, with helioseismic mea…
Spatiotemporal fragmentation and the uncertainties in the solar rotation law
Eurico Covas, Reza Tavakol, Sergei Vorontsov +1
Analyses of recent helioseismic data indicate that the dynamical regimes at the base of the convection zone can be different from those observed at the top, having either significa…
Aspects of the dynamics underlying solar and stellar dynamo models
Reza Tavakol, Eurico Covas
Observations of the Sun and solar-type stars continue to reveal phenomena whose understanding is very likely to require a nonlinear framework. Here we shall concentrate on two such…
