Transits and secondary eclipses of HD 189733 with Spitzer
Eric Agol, Nicolas B. Cowan, James Bushong +4
We present limits on transit timing variations and secondary eclipse depth variations at 8 microns with the Spitzer Space Telescope IRAC camera. Due to the weak limb darkening in t…
A Precise Estimate of the Radius of HD 149026b
Philip Nutzman, David Charbonneau, Joshua N. Winn +4
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,…
A Precise Estimate of the Radius of the Exoplanet HD 149026b from Spitzer Photometry
Philip Nutzman, David Charbonneau, Joshua N. Winn +4
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, allowi…
Multi-Wavelength Constraints on the Day-Night Circulation Patterns of HD 189733b
Heather A. Knutson, David Charbonneau, Nicolas B. Cowan +6
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 previou…
Detection of atmospheric haze on an extrasolar planet: The 0.55 - 1.05 micron transmission spectrum of HD189733b with the Hubble Space Telescope
F. Pont, H. Knutson, R. L. Gilliland +2
The nearby transiting planet HD 189733b was observed during three transits with the ACS camera of the Hubble Space Telescope in spectroscopic mode. The resulting time series of 675…
Observations of Extrasolar Planets During the non-Cryogenic Spitzer Space Telescope Mission
Drake Deming, Eric Agol, David Charbonneau +3
Precision infrared photometry from Spitzer has enabled the first direct studies of light from extrasolar planets, via observations at secondary eclipse in transiting systems. Curre…
