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.

KIC7739728—FK新型Com-Type星级候选人

我们对属于FKCom型恒星的人口稀少的一组物体的参数进行了研究，并对我们的早期研究进行了简要回顾，这些研究致力于寻找这种类型的恒星候选者。我们考虑另一种新的候选星KIC 7739728的数据。该星的光曲线清楚地证明了常规旋转调制的特性，该旋转具有微分性质（参数ΔΩ= 0.010 rad day ^-1），这是一个触发器在活动经度的位置以及恒星表面上光斑位置的周期性变化中都可以观察到这种效应。
