From convective to stellar dynamos
A. Brandenburg, P. J. Käpylä, M. J. Korpi
Convectively driven dynamos with rotation generating magnetic fields on scales large compared with the scale of the turbulent eddies are being reviewed. It is argued that such fiel…
Doppler images of the RS CVn binary II Pegasi during the years 1994-2002
Lindborg, M., Korpi +8
We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. The six maps from 1999-2002 are based on previously unpublished observation…
Magnetorotational instability driven dynamos at low magnetic Prandtl numbers
Petri J. Käpylä, Maarit J. Korpi
Numerical simulations of the magnetorotational instability (MRI) with zero initial net flux in a non-stratified isothermal cubic domain are used to demonstrate the importance of ma…
Angular momentum transport in convectively unstable shear flows
Petri J. Käpylä, Axel Brandenburg, Maarit J. Korpi +2
Angular momentum transport owing to hydrodynamic turbulent convection is studied using local three dimensional numerical simulations employing the shearing box approximation. We de…
Open and closed boundaries in large-scale convective dynamos
P. J. Käpylä, M. J. Korpi, A. Brandenburg
Context. Earlier work has suggested that large-scale dynamos can reach and maintain equipartition field strengths on a dynamical time scale only if magnetic helicity of the fluctua…
Surface temperature maps for II Peg during 1999-2002
M. Lindborg, M. J. Korpi, I. Tuominen +3
The active RS CVn star II Peg has been spectroscopically monitored for almost 18 years with the SOFIN spectrograph at NOT, La Palma, Spain. In this paper we present five new surfac…
