EditorialSupercomputer simulations provide a better picture of the Sun’s magnetic field
The new findings challenge the conventional understanding of solar dynamics and could improve predictions of solar weather in the future

Scientists at Aalto University and the Max Planck Institute for Solar System Research have conducted computer simulations to investigate the existence of a small-scale dynamo in the Sun. The small-scale dynamo is a crucial component in understanding the generation and amplification of the Sun's magnetic fields, which contribute to solar weather events such as coronal mass ejections (CMEs).
Previous studies had raised doubts about the feasibility of a small-scale dynamo in the Sun's conditions, but the new simulations demonstrated its existence and importance in solar dynamics. The findings could aid in predicting major solar events earlier, providing crucial time for preparation. The research team plans to continue studying the interaction between the small-scale and large-scale dynamos and explore lower magnetic Prandtl number values on advanced supercomputers.
