Topological changes in the magnetic field of LQ Hya during an activity minimum
Jyri J. Lehtinen, Maarit J. Käpylä, Thomas Hackman +6
Previous studies have related surface temperature maps, obtained with the Doppler imaging (DI) technique, of LQ Hya with long-term photometry. We compare surface magnetic field map…
Differences in the solar cycle variability of simple and complex active regions during 1996-2018
Shabnam Nikbakhsh, Eija Tanskanen, Maarit Käpylä +1
Aims. Our aim is to examine the solar cycle variability of magnetically simple and complex active region. Methods. We studied simple ( and ) and complex ( and ) acti…
Stellar dynamos in the transition regime: multiple dynamo modes and anti-solar differential rotation
M. Viviani, M. J. Käpylä, J. Warnecke +2
Global and semi-global convective dynamo simulations of solar-like stars are known to show a transition from an anti-solar (fast poles, slow equator) to solar-like (fast equator, s…
