Effect of the viscosity value on the tidally induced TTV for K2-265 b with e = 0.15, Ω∕n = 1.5, and a total transit number of 2 yr. We considered variations of η between theminimum value coming from eccentricity evolution timescale estimations and the maximum value coming from the reference values of Tobie et al. (2019), which were obtained by solving the internal structure equations for the mantle of planets composed by high-pressure silicates.
