Nature Astronomy, Published online: 09 February 2024; doi:10.1038/s41550-023-02183-7 A prominent under-density in the observed radius distribution separates small exoplanets in two categories. The study demonstrates, through planet formation and evolution simulations, that the larger planets, whose composition has been disputed,
