[1] We use limb profiles to investigate the long‐wavelength topography and topographic variance spectrum of Rhea. One‐dimensional variance spectra show a break in slope at a wavelength of ≈300 km; a similar effect is seen on the Moon and may be a signature of an elastic lithosphere having a thickness Te ≈ 10 km. The implied heat flux is ∼15 mWm, much higher than can be explained by radiogenic heating. We use the 1‐D spectral behavior to constrain our solution for the long‐wavelength global… CONTINUE READING
