Abstract
We present a study of the parameters of objects belonging to a sparsely populated group of FKCom-type stars, as well as a brief review of our earlier studies dedicated to the search for stellar candidates of this type. We consider the data for another new candidate-the star KIC 7739728. The light curve of this star clearly demonstrates properties of regular rotational modulation, the rotation exhibits a differential nature (the parameter ΔΩ = 0.010 rad day-1), a flip-flop effect is observed in the positions of active longitudes, as well as cyclic variations of the spot positions on the star’s surface.
