Theoretical stellar shapes at orbital phases 0.00, 0.25, 0.50, and 0.75 derived from TESS photometric data obtained during the time interval BJD 2458697.774–2458699.033. Compared to the earlier Kepler epoch, the later TESS observations are consistent with changes in surface activity patterns inferred from the light-curve modeling. This light-curve and starspot modeling suggests the temporal evolution of stellar magnetic activity.
