A radius valley between migrated steam worlds and evaporated rocky cores
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, may be water-rich planets migrating towards the star, where they become steam worlds.
