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…
Rotational dependence of turbulent transport coefficients in global convective dynamo simulations of solar-like stars
J. Warnecke, M. J. Käpylä
For moderate and slow rotation, magnetic activity of solar-like stars is observed to strongly depend on rotation. These observations do not yet have a solid explanation in terms of…
Spot evolution on LQ Hya during 2006--2017: temperature maps based on SOFIN and FIES data
Elizabeth M. Cole-Kodikara, Maarit J. Käpylä, Jyri J. Lehtinen +4
Context. LQ Hya is one of the most frequently studied young solar analogue stars. Recently, it has been observed to show intriguing behaviour by analysing long-term photometry: dur…
Methods for compressible fluid simulation on GPUs using high-order finite differences
Johannes Pekkilä, Miikka S. Väisälä, Maarit J. Käpylä +2
We focus on implementing and optimizing a sixth-order finite-difference solver for simulating compressible fluids on a GPU using third-order Runge-Kutta integration. Since graphics…
