Context. FK Comae Berenices is a rapidly rotating magnetically active star, the light curve of which is modulated by cool spots on its surface. It was the first star where the “flip-flop” phenomenon was discovered. Since then, flip-flops in the spot activity have been reported in many other stars. Follow-up studies with increasing length have shown, however, that the phenomenon is more complex than was thought right after its discovery. Aims. Therefore, it is of interest to perform a more… 
Multiperiodicity, modulations and flip-flops in variable star light curves: II. Analysis of II Pegasus photometry during 1979-2010
Aims. According to previously published Doppler images of the magnetically active primary giant component of the RS CVn binary II Peg, the surface of the star was dominated by one single active
Starspot activity of HD 199178
Context. Studying the spots of late-type stars is crucial for distinguishing between the various proposed dynamo mechanisms believed to be the main cause of starspot activity. For this research it is
Study of FK Comae Berenices: VII. Correlating photospheric and chromospheric activity
We study the connection between the chromospheric and photospheric behaviour of the active late-type star FK Comae. We use spot temperature modelling, light curve inversion based on narrow- and
Spot activity of the RS Canum Venaticorum star σ Geminorum
Aims. We model the photometry of RS CVn star σ Geminorum to obtain new information on the changes of the surface starspot distribution, that is, activity cycles, differential rotation, and active

We study LQ Hya photometry for 1982-2014 with the carrier fit (CF) -method and compare our results to earlier photometric analysis and recent Doppler imaging maps. We first utilize different types of
Spots and activity cycles of the star FKCom—2013–2015 data analysis
We present an analysis of new photometric and spectropolarimetric observations of a chromospherically active star FKCom. Based on this observational data and the data from the literature sources,
General Model for Light Curves of Chromospherically Active Binary Stars
The starspots on the surface of many chromospherically active binary stars concentrate on long--lived active longitudes separated by 180 degrees. The activity shifts between these two longitudes, the
Doppler imaging of LQ Hydrae for 1998-2002
Aims. We study the spot distribution on the surface of LQ Hya during the observing seasons October 1998-November 2002. We look for persistent active longitudes, trends in the level of spot activity
Doppler images of DI Piscium during 2004–2006
TLDR
It can be concluded that the spot activity level of the star is variable over time, as compared with earlier Doppler maps of DI Psc, which seems to be in a low activity state especially during the observing season of July–August 2004.
