Journal ArticleDOI
A temperature and abundance retrieval method for exoplanet atmospheres
Nikku Madhusudhan,Sara Seager +1 more
TL;DR: In this paper, a parametric pressure-temperature (P-T) profile coupled with line-by-line radiative transfer, hydrostatic equilibrium, and energy balance, along with prescriptions for non-equilibrium molecular composition and energy redistribution was developed.
Journal ArticleDOI
INFRARED TRANSMISSION SPECTROSCOPY OF THE EXOPLANETS HD 209458b AND XO-1b USING THE WIDE FIELD CAMERA-3 ON THE HUBBLE SPACE TELESCOPE
Drake Deming,Drake Deming,A. Wilkins,Peter R. McCullough,Adam Burrows,Jonathan J. Fortney,Eric Agol,Eric Agol,Ian Dobbs-Dixon,Ian Dobbs-Dixon,Nikku Madhusudhan,Nicolas Crouzet,Jean-Michel Desert,Ronald L. Gilliland,Korey Haynes,Korey Haynes,Heather Knutson,Michael R. Line,Zazralt Magic,Avi Mandell,Sukrit Ranjan,David Charbonneau,Mark Clampin,Sara Seager,Adam P. Showman +24 more
TL;DR: In this paper, the authors reported WFC3 spectroscopy of the giant planets HD 209458b and XO-1b in transit, using spatial scanning mode for maximum photon-collecting efficiency.

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
C/o ratio as a dimension for characterizing exoplanetary atmospheres
TL;DR: In this paper, the carbon-to-oxygen (C/O) ratio is considered as an important second dimension for characterizing exoplanetary atmospheres, since the C/O ratio critically influences the relative concentrations of several spectroscopically dominant species.
