Characterisation of starspot structure and differential rotation of Kepler-411
Mikko Tuomi, András Haris, Thomas Hackman
Starspots and their movements on stellar surfaces enable investigating the mechanisms of stellar magnetic activity. Information on the spot distribution and differential rotation p…

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…

Homogeneous search for spot transits in Kepler and TESS photometry of K M-type main-sequence stars
András Haris, Mikko Tuomi, Thomas Hackman
Late-type stars are known to host numerous exoplanets, and their photometric variability, primarily caused by rotational modulation, provides a unique opportunity to study starspot…
