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…
Hunting down the cause of solar magnetism
M. Viviani, A. Prabhu, J. Warnecke +4
To understand solar and stellar dynamos combining local and global numerical modelling with long-term observations is a challenging task: even with state of the art computational m…
Interaction of large- and small-scale dynamos in isotropic turbulent flows from GPU-accelerated simulations
Miikka S. Väisälä, Johannes Pekkilä, Maarit J. Käpylä +3
Magnetohydrodynamical (MHD) dynamos emerge in many different astrophysical situations where turbulence is present, but the interaction between large-scale (LSD) and small-scale dyn…
Small-Scale Dynamo in Supernova-Driven Interstellar Turbulence
Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Kapyla +1
Magnetic fields grow quickly even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in the interstellar medium of galaxies. Many studies have focused…
The Pencil Code, a modular MPI code for partial differential equations and particles: multipurpose and multiuser-maintained
A. Brandenburg, A. Johansen, P. A. Bourdin +34
The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equ…
Common dynamo scaling in slowly rotating young and evolved stars
Jyri J. Lehtinen, Federico Spada, Maarit J. Käpylä +2
One interpretation of the activity and magnetism of late-type stars is that these both intensify with decreasing Rossby number up to a saturation level, suggesting that stellar dyn…
