Location of the HIP 29442 planets (purple markers) in the orbital period-radius diagram in relation to the known exoplanet population, plotted using the Planets exoplanet catalogue. The transparent pink points show the planetary parameters derived by Damasso et al. (2023). The location of the radius valley is indicated in dark grey using the fit from Ho & Van Eylen (2023). The area shaded in light grey is the radius cliff beyond 3 R_⊕.
