Among Neptunian mass exoplanets (20−50 M _⊕ ), puffy hot Neptunes are extremely rare, and their unique combination of low mass and extended radii implies very low density ( ρ < 0.3 g cm ^−3 ). Over the last decade, only a few puffy planets hav

Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley offers a unique means to establish whether the radius valley emerges from an atmospheric mass loss process or is imprinted by planet formation itself. We p
