Abstract (from CDS):

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 planet, a mass of 7.3±0.5 Jupiter masses (MJ), and a radius of 1.28±0.08 Jupiter radii (RJ). Its mean density of 4.6 g/cm3 is one of the highest known for planets with periods less than three days. We obtained three secondary eclipse light curves with the Spitzer Space Telescope. The eclipse depths from the best jointly fit model are 0.224%±0.018% at 4.5 µm and 0.181%±0.022% at 8.0 µm. The corresponding brightness temperatures are 2212±94 K and 1590±116 K. A slight ambiguity between systematic models suggests a conservative 3.6 µm eclipse depth of 0.19%±0.01% and brightness temperature of 2242±55 K. Although extremely irradiated, WASP-14b does not show any distinct evidence of a thermal inversion. In addition, the present data nominally favor models with day-night energy redistribution less than ∼30%. The current data are generally consistent with oxygen-rich as well as carbon-rich compositions, although an oxygen-rich composition provides a marginally better fit. We confirm a significant eccentricity of e = 0.087±0.002 and refine other orbital parameters.
