Interferometric Images of the Starspot Evolution of Andromedae
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +21
The evolution of starspots of the giant primaries of RS CVn systems is typically detected indirectly with photometric and spectroscopic monitoring. These observations suggest slowl…
A star under multiple influences. Magnetic activity in V815 Her, a compact 2+2 hierarchical system
Zs. Kovari, K. G. Strassmeier, L. Kriskovics +7
We are conducting a comprehensive investigation of V815 Her using photometric and spectroscopic data to understand the origin of the activity and what influences it in the short an…
Superflares on the late-type giant KIC 2852961 -- Scaling effect behind flaring at different energy levels
Zs. Kővári, K. Oláh, M. N. Günther +7
The most powerful superflares reaching 10erg bolometric energy are from giant stars. The mechanism behind flaring is supposed to be the magnetic reconnection, which is close…
Magnetic activity of the young solar analogue V1358 Ori
L. Kriskovics, Zs. Kővári, K. Vida +3
Young, fast rotating single stars can show dramatically different magnetic signatures and levels of magnetic activity as compared with the Sun. While losing angular momentum due to…
The contact binary VW Cephei revisited: surface activity and period variation
T. Mitnyan, A. Bódi, T. Szalai +7
Context. Despite the fact that VW Cephei is one of the well-studied contact binaries in the literature, there is no fully consistent model available that can explain every observed…
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.…
