The Broadband Infrared Emission Spectrum of the Exoplanet TrES-3 (2009)
Fressin, Francois, Knutson, Heather A., Charbonneau, David, O'Donovan, Francis T., Burrows, Adam, Deming, Drake, ...
We use the Spitzer Space Telescope to estimate the dayside thermal emission of the exoplanet TrES-3 integrated in the 3.6, 4.5, 5.8, and 8.0 micron bandpasses of the Infrared Array Camera (IRAC)...
Detection of Planetary Emission from the Exoplanet TrES-2 using Spitzer /IRAC (2009)
O'Donovan, Francis T., Charbonneau, David, Harrington, Joseph, Seager, Sara, Madhusudhan, N., Deming, Drake, ...
With the recent torrent of discoveries of new transiting planets, there have been ample candidates for observations using the Spitzer Space Telescope. We present here the results of our observations...
The 8 Micron Phase Variation of the Hot Saturn HD 149026b (2009)
Knutson, Heather A., Charbonneau, David, Cowan, Nicolas B., Fortney, Jonathan J., Showman, Adam P., Agol, Eric, ...
We monitor the star HD 149026 and its Saturn-mass planet at 8.0 micron over slightly more than half an orbit using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. We find an increase...
Detection of a Temperature Inversion in the Broadband Infrared Emission Spectrum of TrES-4 (2008)
Knutson, Heather A., Charbonneau, David, Burrows, Adam, O'Donovan, Francis T., Mandushev, Georgi
We estimate the strength of the bandpass-integrated thermal emission from the extrasolar planet TrES-4 at 3.6, 4.5, 5.8, and 8.0 micron using the Infrared Array Camera (IRAC) on the Spitzer Space...
Showman, Adam P., Fortney, Jonathan J., Lian, Yuan, Marley, Mark S., Freedman, Richard S., Knutson, Heather A., ...
We present global, three-dimensional numerical simulations of HD 189733b and HD 209458b that couple the atmospheric dynamics to a realistic representation of non-gray cloud-free radiative transfer....
A Precise Estimate of the Radius of HD 149026b (2008)
Nutzman, Philip, Charbonneau, David, Winn, Joshua N., Knutson, Heather A., Fortney, Jonathan J., Holman, Matthew J., ...
We present Spitzer 8 micron transit observations of the extrasolar planet system HD 149026. At this wavelength, transit light curves are weakly affected by stellar limb-darkening, allowing for a...
A Precise Estimate of the Radius of the Exoplanet HD 149026b from Spitzer Photometry (2008)
Nutzman, Philip, Charbonneau, David, Winn, Joshua N., Knutson, Heather A., Fortney, Jonathan J., Holman, Matthew J., ...
We present Spitzer 8 micron transit observations of the extrasolar planet HD 149026b. At this wavelength, transit light curves are weakly affected by stellar limb-darkening, allowing for a simpler...
Multi-Wavelength Constraints on the Day-Night Circulation Patterns of HD 189733b (2008)
Knutson, Heather A., Charbonneau, David, Cowan, Nicolas B., Fortney, Jonathan J., Showman, Adam P., Agol, Eric, ...
We present new Spitzer observations of the phase variation of the hot Jupiter HD 189733b in the MIPS 24 micron bandpass, spanning the same part of the planet's orbit as our previous observations in...
The Broadband Infrared Emission Spectrum of the Exoplanet HD 189733b (2008)
Charbonneau, David, Knutson, Heather A., Barman, Travis, Allen, Lori E., Mayor, Michel, Megeath, S. Thomas, ...
We present Spitzer Space Telescope time series photometry of the exoplanet system HD 189733 spanning two times of secondary eclipse, when the planet passes out of view behind the parent star. We...
Knutson, Heather A., Charbonneau, David, Allen, Lori E., Burrows, Adam, Megeath, S. Thomas
We estimate the strength of the bandpass-integrated thermal emission from the extrasolar planet HD 209458b at 3.6, 4.5, 5.8, and 8.0 microns using the Infrared Array Camera (IRAC) on the Spitzer...
A Ground-Based Search for Thermal Emission from the Exoplanet TrES-1 (2007)
Knutson, Heather A., Charbonneau, David, Deming, Drake, Richardson, L. Jeremy
Eclipsing planetary systems give us an important window on extrasolar planet atmospheres. By measuring the depth of the secondary eclipse, when the planet moves behind the star, we can estimate the...
A map of the day-night contrast of the extrasolar planet HD 189733b (2007)
