Journal ArticleDOI
Understanding the mass-radius relation for sub-neptunes: radius as a proxy for composition
TL;DR: In this paper, the authors provide model radii for low-mass rocky super-Earths with hydrogen-helium envelopes, with envelope fractions 0.01-20 M ⊕, with levels of irradiation 0.1-1000 times Earth's, and ages from 100 Myr to 10 Gyr.
Journal ArticleDOI
A PRECISE WATER ABUNDANCE MEASUREMENT FOR THE HOT JUPITER WASP-43b
Laura Kreidberg,Jacob L. Bean,Jean-Michel Desert,Michael R. Line,Jonathan J. Fortney,Nikku Madhusudhan,Kevin B. Stevenson,Adam P. Showman,David Charbonneau,Peter R. McCullough,Sara Seager,Adam Burrows,Gregory W. Henry,Michael H. Williamson,Tiffany Kataria,Derek Homeier +15 more
TL;DR: In this paper, the water abundance in the atmosphere of the 2 MJup short-period exoplanet WASP-43b was determined based on thermal emission and transmission spectroscopy measurements obtained with the Hubble Space Telescope.
Journal ArticleDOI

Laura Kreidberg,Michael R. Line,Jacob L. Bean,Kevin B. Stevenson,Jean-Michel Desert,Nikku Madhusudhan,Jonathan J. Fortney,Joanna K. Barstow,Gregory W. Henry,Michael H. Williamson,Adam P. Showman +10 more
TL;DR: In this article, a near-infrared transmission spectrum for WASP-12b based on six transit observations with the Hubble Space Telescope/Wide Field Camera 3 (HST-WFC) was reported.
Journal ArticleDOI
Gaseous mean opacities for giant planet and ultracool dwarf atmospheres over a range of metallicities and temperatures
Richard S. Freedman,Richard S. Freedman,Jacob Lustig-Yaeger,Jonathan J. Fortney,Roxana Lupu,Mark S. Marley,Katharina Lodders +6 more
TL;DR: In this article, the authors presented new calculations of Rosseland and Planck gaseous mean opacities relevant to the atmospheres of giant planets and ultracool dwarfs.
Journal ArticleDOI
Masses, Radii, and Cloud Properties of the HR 8799 Planets
Mark S. Marley,Didier Saumon,Michael C. Cushing,Andrew S. Ackerman,Jonathan J. Fortney,Richard S. Freedman +5 more
TL;DR: In this paper, the authors compare the available data to the predictions of their own set of atmospheric and evolution models that have been extensively tested against field L and T dwarfs, including the reddest L dwarfs.
