Hycean Worlds "Hycean worlds are a class of water-rich sub-Neptunes with planet-wide oceans underlying H 2 -rich atmospheres. Such planets have a significantly wider habitable zone compared to terrestrial planets. With expected radii between 1-2.6 R ⊕ for masses between 1-10 M ⊕ , Hycean planets represent a habitable subset of temperate sub-Neptunes that allow for a vast diversity of atmospheric and internal structures... Such planets are also potentially abundant in the exoplanet population given the predominance of exoplanets in the sub-Neptune regime" (pp. 1-2).
