A Knee-Point in the Rotation-Activity Scaling of Late-type Stars with a Connection to Dynamo Transitions
Jyri J. Lehtinen, Maarit J. Käpylä, Nigul Olspert +1
The magnetic activity of late-type stars is correlated with their rotation rates. Up to a certain limit, stars with smaller Rossby numbers, defined as the rotation period divided b…
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…
Hidden magnetic fields of young suns
O. Kochukhov, T. Hackman, J. J. Lehtinen +1
Global magnetic fields of active solar-like stars are nowadays routinely detected with spectropolarimetric measurements and are mapped with Zeeman-Doppler imaging (ZDI). However, d…
