Antisolar differential rotation of the K1-giant sigma Geminorum revisited
Zs. Kovari, L. Kriskovics, A. Künstler +6
Context. Surface differential rotation and other global surface flows on magnetically active stars are among the observable manifestations of the stellar dynamo working underneath.…
Magnitude-range brightness variations of overactive K giants
K. Oláh, A. Moór, Zs. Kővári +4
We study three representative, overactive spotted K giants (IL Hya, XX Tri, and DM UMa) known to exhibit V-band light variations between 0.65-1.05 mags. Our aim is to find the orig…
Observing dynamos in cool stars
Zsolt Kovari, Katalin Olah
The main aim of this paper is to introduce the most important observables that help us to investigate stellar dynamos and compare those to the modeling results. We give an overview…
Lithium enrichment on the single active K1-giant DI Piscium -- Possible joint origin of differential rotation and Li enrichment
L. Kriskovics, Zs. Kővári, K. Vida +2
We investigate the surface spot activity of the rapidly rotating, lithium-rich active single K-giant DI Psc to measure the surface differential rotation and understand the mechanis…
