Iterative Poisson Solvers for Self-gravity with the GPU Code Astaroth
Ruben Krasnopolsky, Touko Puro, Wei-Wen Li +5
We present the development and benchmarking of Poisson solvers for graphics processing units (GPUs). Implemented in the Astaroth platform, the solvers feature high computational ef…
Asymptotic behaviour of galactic small-scale dynamos at modest magnetic Prandtl number
Frederick A. Gent, Mordecai-Mark Mac Low, Maarit J. Korpi-Lagg +2
Magnetic fields are critical at many scales to galactic dynamics and structure, including multiphase pressure balance, dust processing, and star formation. Dynamo action determines…
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…
Compressible test-field method and its application to shear dynamos
Maarit J. Käpylä, Matthias Rheinhardt, Axel Brandenburg
In this study we present a compressible test-field method (CTFM) for computing effect and turbulent magnetic diffusivity tensors, as well as those relevant for mean ponderomoti…
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…
