Small-scale and large-scale dynamos in global convection simulations of solar-like stars
Jörn Warnecke, Maarit J. Korpi-Lagg, Matthias Rheinhard +2
It has been recently shown numerically that a small-scale dynamo (SSD) instability could be possible in solar-like low magnetic Prandtl number plasmas. It has been proposed that th…
Numerical evidence for a small-scale dynamo approaching solar magnetic Prandtl numbers
Jörn Warnecke, Maarit J. Korpi-Lagg, Frederick A. Gent +1
Magnetic fields on small scales are ubiquitous in the universe. Though they can often be observed in detail, their generation mechanisms are not fully understood. One possibility i…
From convective stellar dynamo simulations to Zeeman-Doppler images
Thomas Hackman, Oleg Kochukhov, Mariangela Viviani +3
Zeeman-Doppler imaging (ZDI) is used to reconstruct the surface magnetic field of late-type stars from high resolution spectropolarimetric observations. The results are usually des…
Simulations of solar and stellar dynamos and their theoretical interpretation
Petri J. Käpylä, Matthew K. Browning, Allan Sacha Brun +2
We review the state of the art of three dimensional numerical simulations of solar and stellar dynamos. We summarize fundamental constraints of numerical modelling and the techniqu…
Constraining Global Solar Models through Helioseismic Analysis
Andrey M. Stejko, Alexander G. Kosovichev, Nicholas A. Featherstone +4
Global hydrodynamic simulations of internal solar dynamics have focused on replicating the conditions for solar-like differential rotation and meridional circulation using the resu…
Investigating global convective dynamos with mean-field models: full spectrum of turbulent effects required
Jörn Warnecke, Matthias Rheinhardt, Mariangela Viviani +3
The role of turbulent effects for dynamos in the Sun and stars continues to be debated. Mean-field (MF) theory provides a broadly used framework to connect these effects to fundame…
