Broad exploration of the TTV as a function of four parameters: (a) planetary mass, (b) planetary radius, (c) stellar mass, and (d) semi-major axis values. We considered a total timespan of 2 yr in all the simulations. In each panel of the figure, we tuned each parameter individually and considered the nominal values of the K2-265 b system for the remaining ones (see Table 2). Moreover, in all cases shown here, we considered a 3/2 spin-orbit resonant state for the planet as well as an eccentricity of 0.15 in order to maximize the effects of the TTVs.
