The Atmosphere and Interior Structure of HAT-P-13b from Spitzer Secondary Eclipses
Ryan A. Hardy, Joseph Harrington, Matthew R. Hardin +6
We present {\em Spitzer} secondary-eclipse observations of the hot Jupiter HAT-P-13 b in the 3.6 {\micron} and 4.5 {\micron} bands. HAT-P-13 b inhabits a two-planet system with a c…
WASP-8b: Characterization of a Cool and Eccentric Exoplanet with Spitzer
Patricio Cubillos, Joseph Harrington, Nikku Madhusudhan +6
WASP-8b has 2.18 times Jupiter's mass and is on an eccentric () 8.16-day orbit. With a time-averaged equilibrium temperature of 948 K, it is one of the least-irradiated hot…
Spitzer observations of the thermal emission from WASP-43b
Jasmina Blecic, Joseph Harrington, Nikku Madhusudhan +9
WASP-43b is one of the closest-orbiting hot Jupiters, with a semimajor axis of a = 0.01526 +/- 0.00018 AU and a period of only 0.81 days. However, it orbits one of the coolest star…
Two nearby sub-Earth-sized exoplanet candidates in the GJ 436 system
Kevin B. Stevenson, Joseph Harrington, Nate B. Lust +8
We report the detection of UCF-1.01, a strong exoplanet candidate with a radius 0.66 +/- 0.04 times that of Earth (R_{\oplus}). This sub-Earth-sized planet transits the nearby M-dw…
Thermal Emission of WASP-14b Revealed with Three Spitzer Eclipses
Jasmina Blecic, Joseph Harrington, Nikku Madhusudhan +10
Exoplanet WASP-14b is a highly irradiated, transiting hot Jupiter. Joshi et al. calculate an equilibrium temperature Teq of 1866 K for zero albedo and reemission from the entire pl…
Transit and Eclipse Analyses of Exoplanet HD 149026b Using BLISS Mapping
Kevin B. Stevenson, Joseph Harrington, Jonathan J. Fortney +7
The dayside of HD 149026b is near the edge of detectability by the Spitzer Space Telescope. We report on eleven secondary-eclipse events at 3.6, 4.5, 3 x 5.8, 4 x 8.0, and 2 x 16 m…
High C/O Ratio and Weak Thermal Inversion in the Very Hot Atmosphere of Exoplanet WASP-12b
Nikku Madhusudhan, Joseph Harrington, Kevin B. Stevenson +16
The carbon-to-oxygen ratio (C/O) in a planet provides critical information about its primordial origins and subsequent evolution. A primordial C/O greater than 0.8 causes a carbide…
Possible thermochemical disequilibrium in the atmosphere of the exoplanet GJ 436b
Kevin B. Stevenson, Joseph Harrington, Sarah Nymeyer +7
The nearby extrasolar planet GJ 436b--which has been labelled as a 'hot Neptune'--reveals itself by the dimming of light as it crosses in front of and behind its parent star as see…
Spitzer Secondary Eclipses of WASP-18b
Sarah Nymeyer, Joseph Harrington, Ryan A. Hardy +16
The transiting exoplanet WASP-18b was discovered in 2008 by the Wide Angle Search for Planets (WASP) project. The Spitzer Exoplanet Target of Opportunity Program observed secondary…
On the Orbit of Exoplanet WASP-12b
Christopher J. Campo, Joseph Harrington, Ryan A. Hardy +17
We observed two secondary eclipses of the exoplanet WASP-12b using the Infrared Array Camera on the Spitzer Space Telescope. The close proximity of WASP-12b to its G-type star resu…
