Polarimetric light-curve set of a ringed and ringless HIP 41378 f planet for different values of b and ϖ as functions of ν. The magenta curves pertain to the ringless puffed-up planet, and the black curves show the ringed planet model, but without a ring, using the parameter values of Akinsanmi et al. (2020). All curves use the same orbital inclination and stellar properties, but the magenta curve has a different semimajor axis (a/r_* = 231.6). In the F_pol plot, the magenta curve has been omitted as it has the same shape as the black curve, except with maximum values up to 0.0015 ppm. In the P plot, the magenta and black curves overlap.
