O článku:
In 2017-2018, using a robotic wide-field telescope at the Zvenigorod Observatory of INASAN, we carried out new observations of several active late type stars including a rapidly rotating dwarf LO Peg and a rapidly rotating giant — king of spin FK Com. New observations of stars carried out in the V filter allowed to obtain new data for the long-term variability cycles of these objects. Significant changes in the shape of the power spectrum were noted after taking into account our new observations. From the light curves we made restoration of the temperature inhomogeneities on stellar surfaces and determined positions of the active longitudes. The obtained measurements indicate the ongoing evolution of moving active regions and the switching phenomenon(flip-flop) of the positions of active longitudes for FK Com.
