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.
Journal ArticleDOI
An ultrahot gas-giant exoplanet with a stratosphere
Thomas M. Evans,David K. Sing,Tiffany Kataria,Jayesh M. Goyal,Nikolay Nikolov,Hannah R. Wakeford,Drake Deming,Mark S. Marley,David S. Amundsen,David S. Amundsen,Gilda E. Ballester,Joanna K. Barstow,Lotfi Ben-Jaffel,Vincent Bourrier,Lars A. Buchhave,Ofer Cohen,David Ehrenreich,Antonio García Muñoz,Gregory W. Henry,Heather Knutson,Panayotis Lavvas,Alain Lecavelier des Etangs,Nikole K. Lewis,Mercedes Lopez-Morales,Avi Mandell,Jorge Sanz-Forcada,Pascal Tremblin,Roxana Lupu +27 more
TL;DR: In this article, the authors reported a near-infrared thermal spectrum for the ultrahot gas giant WASP-121b, which has an equilibrium temperature of approximately 2,500 kelvin.
Journal ArticleDOI
The Complete Transmission Spectrum of WASP-39b with a Precise Water Constraint
Hannah R. Wakeford,Hannah R. Wakeford,David K. Sing,Drake Deming,Nikole K. Lewis,Nikole K. Lewis,Jayesh M. Goyal,Tom J. Wilson,Joanna K. Barstow,Tiffany Kataria,Benjamin Drummond,Thomas M. Evans,Aarynn L. Carter,Nikolay Nikolov,Heather A. Knutson,Gilda E. Ballester,Avi Mandell +16 more
TL;DR: WASP-39b is a hot Saturn-mass exoplanet with a predicted clear atmosphere based on observations in the optical and infrared as mentioned in this paper, which is relatively high with respect to the currently established mass-metallicity trends.
Journal ArticleDOI
An absolute sodium abundance for a cloud-free 'hot Saturn' exoplanet
Nikolay Nikolov,David K. Sing,David K. Sing,Jonathan J. Fortney,Jayesh M. Goyal,Benjamin Drummond,Thomas M. Evans,Neale P. Gibson,E. J. W. de Mooij,Zafar Rustamkulov,Hannah R. Wakeford,Barry Smalley,Adam J. Burgasser,Coel Hellier,Christiane Helling,Christiane Helling,Nathan J. Mayne,Nikku Madhusudhan,Tiffany Kataria,J. Baines,Aarynn L. Carter,Gilda E. Ballester,Joanna K. Barstow,J. McCleery,Jessica Spake +24 more
TL;DR: The optical transmission spectrum for the ‘hot Saturn’ exoplanet WASP-96b reveals a clear atmosphere, an atmospheric sodium abundance and hence its metallicity, which is consistent with the metalicity trend observed in Solar System planets and exoplanets.
Journal ArticleDOI
The effects of consistent chemical kinetics calculations on the pressure-temperature profiles and emission spectra of hot Jupiters
Benjamin Drummond,Pascal Tremblin,Pascal Tremblin,Isabelle Baraffe,Isabelle Baraffe,David S. Amundsen,David S. Amundsen,David S. Amundsen,Nathan J. Mayne,Olivia Venot,Jayesh M. Goyal +10 more
TL;DR: In this paper, the authors investigated the impact of calculating non-equilibrium chemical abundances consistently with the temperature structure for the atmospheres of highly-irradiated, close-in gas giant exoplanets.
