The rotation-magnetism relationship in solar-type stars. Constraining magnetic flux emergence rates
Emre Isik, Sami K. Solanki, Natalie A. Krivova +1
The rotation-activity relationship of G-type stars results from surface magnetic fields emerging from the interior. How the magnetic flux and its emergence rate scale with rotation…

Quantifying sunspot group nesting with density-based unsupervised clustering
Nurdan Karapinar, Emre Isik, Natalie A. Krivova +1
Sunspot groups often emerge in spatial-temporal clusters, known as nests or complexes of activity. Quantifying how frequently such nesting occurs is important for understanding the…

The stellar activity-rotation-age relationship under the lens of asteroseismology
C. Pezzotti, J. Bétrisey, G. Buldgen +6
In low-mass stars, the connection between magnetic activity, rotation period, and age provides key insights into the functioning of dynamos. Fully understanding the activity-rotati…
