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,…
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…
Surface activity of the G dwarf primary in the quaternary star system V815 Her
Zsolt Kővári, Klaus G. Strassmeier, Tamás Borkovits +4
We investigate the magnetic activity of the G dwarf primary star in the multiple system V815 Herculis. Recently, TESS Sector 26 data have revealed that V815 Her is in fact a four-s…
KIC 2852961 -- a superflaring red monster in the Kepler field
Zs. Kővári, K. Oláh, M. N. Günther +3
Superflares on giant stars have up to 100,000 times more energy than the high energy solar flares. However, it is disputed, whether scaling up a solar-type dynamo could explain suc…
Towards the true number of flaring giant stars in the Kepler field. Are there flaring specialities associated with the giant nature?
K. Oláh, Zs. Kővári, M. N. Günther +4
We aim to give a reliable estimate of the number of flaring giant stars in the Kepler field. By analyzing the flaring activity of these stars we explore their flare statistics and…
Photospheric and chromospheric activity in V405 And: An M dwarf binary with components on the two sides of the full convection limit
K. Vida, K. Oláh, Zs. Kővári +4
We investigate the fast-rotating (P_orb=P_rot=0.465d), active dwarf binary V405 And (M0V+M5V) using photometric BV(RI)_C and optical spectroscopic data. The light variation is caus…
