Astroinformatics

Astroinformatics group conducts research on astrophysical objects, such as the Sun, other stars, accretion disks, and galaxies, using state-of-the-art numerical simulations and data-analysis techniques. These include simulation tools accelerated with graphics processing units, and data-analysis tools employing machine learning. Our goals include understanding, predicting, and mitigating the harmful effects from solar magnetic activity.

Magnetic fields residing in the convection zone of a solar-like star modelled

Video description: With the aid of computer simulations, we can study how the subsurface magnetic fields are generated inside the stars. The key role is played by convective turbulence, added with large-scale plasma motions. These effects together induce magnetic fields that eventually cause all magnetic activity of stars.

The video has been produced by Petri Käpylä.
