TESS flares and chromospheric variability in the Pleiades, the Hyades, and Praesepe
A. Görgei, K. Vida, B. Seli +5
Magnetic activity is a result of the interaction between rotation and dynamo processes in cool stars with outer convection zones. Since open cluster members share a common age, dis…
Sub-second cadence structure of optical flares on AD Leo
B. Schmercz, B. Seli, K. Vida +4
Stellar flares are sudden brightenings caused by magnetic reconnection and are frequently observed on late-type stars. High-cadence photometry of flares provides valuable insights…
Magnetic activity on the young Sun: a case study of EK Draconis
A. Görgei, L. Kriskovics, K. Vida +8
Context. Young, solar analogue stars provide key insights into the early stages of stellar evolution, particularly in terms of magnetic activity and rotation. Their rapid rotation,…
Four decades of photometry of XX Trianguli, `the most spotted star' in the sky
Zs. Kővári, K. G. Strassmeier, K. Oláh +3
Over the past 40 years the brightness variations of XX Tri, a single line RS CVn type binary system with a synchronized K-giant primary, has exceeded one magnitude in the V band. A…
Starspots on eclipsing giant stars I.: The sample and eclipse mapping examples
K. Oláh, B. Seli, A. Haris +12
Spotted stars in eclipsing binary systems allow us to gather significant information about the stellar surface inhomogeneities that is otherwise impossible from only photometric da…
Magnetic activity under tidal influences in the 2+2~hierarchical quadruple system V815 Herculis
Zs. Kővári, K. G. Strassmeier, L. Kriskovics +5
Tidal forces in close binaries and multiple systems that contain magnetically active component are supposed to influence the operation of magnetic dynamo. Through synchronization t…
Characteristics of flares on giant stars
Katalin Oláh, Bálint Seli, Zsolt Kővári +2
Although late-type dwarfs and giant stars are substantially different, their flares are thought to originate in similar physical processes and differ only by a scale factor in the…
Eclipsing Spotted Giant Star With K2 and Historical Photometry
K. Oláh, S. Rappaport, T. Borkovits +15
Context. Stars can maintain their observable magnetic activity from the PMS to the tip of the red giant branch. However, the number of known active giants is much lower than active…
