Water-rich sub-Neptunes and rocky super-Earths around different stars: Radii shaped by volatile partitioning, formation, and evolution

Despite precise characterization measurements, the nature of planets with radii between 2 and 4 Earth radii -- sub-Neptunes -- remains unknown due to degeneracies in interior models. Nevertheless, the field has compiled an impressive ensemble of small planets with measured masses...
