A continuum from clear to cloudy hot-Jupiter exoplanets without primordial water depletion
David K. Sing,Jonathan J. Fortney,Nikolay Nikolov,Hannah R. Wakeford,Tiffany Kataria,Thomas M. Evans,Suzanne Aigrain,Gilda E. Ballester,Adam Burrows,Drake Deming,Jean-Michel Desert,Neale P. Gibson,Gregory W. Henry,Catherine M. Huitson,Heather Knutson,Alain Lecavelier des Etangs,Frederic Pont,Adam P. Showman,Alfred Vidal-Madjar,Michael H. Williamson,Paul Wilson +20 more
TL;DR: The difference between the planetary radius measured at optical and infrared wavelengths is an effective metric for distinguishing different atmosphere types, so that strong water absorption lines are seen in clear-atmosphere planets and the weakest features are associated with clouds and hazes.

TL;DR: A detection of helium absorption at 10,833 Å on the exoplanet WASP-107b reveals that its atmosphere is extended and eroding, and demonstrates a new way to study upper exoplanetary atmospheres.
