Abstract
On the base of the lists of objects from the archives of the LAMOST survey telescope and the TESS, Kepler and K2 space missions we study the manifestations of the spot activity of solar-type stars with exoplanets with pronounced flare activity. Diagrams of the form {spottedness parameter S–flare energy} and {spottedness parameter S-rotation period} are considered. As in the case of solar-type stars with superflares and other active stars among the objects under consideration the most active ones rotate faster, they are younger and the area of spots on their surface is greater. The difference is that the spottedness of most stars with planetary systems does not reach the maximum values of the spottedness parameter for stars with superflares. Among the 6 objects with the light curves available in the TESS mission archive the solar-type star TIC 410214986 (DS Tuc) with pronounced photospheric and chromospheric activity which is a member of the Tucana-Horologium group with an age of about 45 million years attracts special attention.
