Dependence of the large-scale vortex instability on latitude, stratification and domain size
Maarit J. Mantere, Petri J. Käpylä, Thomas Hackman
In an earlier study, we reported on the excitation of large-scale vortices in Cartesian hydrodynamical convection models subject to rapid enough rotation. In that study, the condit…
Doppler images of II Pegasi for 2004-2010
Thomas Hackman, Maarit J. Mantere, Marjaana Lindborg +4
Aims. We study the spot activity of II Peg during the years 2004-2010 to determine long- and short-term changes in the magnetic activity. In a previous study, we detected a persist…
Starspots due to large-scale vortices in rotating turbulent convection
P. J. Käpylä, M. J. Mantere, T. Hackman
We study the generation of large-scale vortices in rotating turbulent convection by means of Cartesian direct numerical simulations. We find that for sufficiently rapid rotation, c…
