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…
Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle
Maximilian N. Günther, David A. Berardo, Elsa Ducrot +37
New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 (scallop shells) and TESS (complex…
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…
Cycle times of early M dwarf stars: mean field models versus observations
Manfred Küker, Günther Rüdiger, Katalin Oláh +1
Observations of early-type M stars suggest that there are two characteristic cycle times, one of order one year for fast rotators ( day) and another of order four…
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…
Surface magnetic activity of the fast-rotating G5-giant IN Comae, central star of the faint planetary nebula LoTr 5
Zs. Kővári, K. G. Strassmeier, K. Oláh +8
On the AGB, low to intermediate mass stars blow away their outer envelopes, forming planetary nebulae. Interaction between the planetary nebula and its central progenitor is poorly…
