ULTRACAM z′-band detection of the secondary eclipse of WASP-12b
We present z′-band secondary eclipse photometry of the highly irradiated hot Jupiter WASP12b using ULTRACAM on the 4.2 m William Herschel Telescope. We measure a decrease in flux of δ = 0.130 ± 0.013 per cent during the passage of the planet behind the star, which is significantly deeper than the previous measurement at this wavelength (0.082± 0.015 per cent). Our secondary eclipse is best fitt...
متن کاملSecondary Eclipse Photometry of the Exoplanet Wasp-5b With
We present secondary eclipse photometry of the extrasolar planet WASP-5b taken in the 3.6 and 4.5μm bands with the Spitzer Space Telescope’s Infrared Array Camera as part of the extended warm mission. By estimating the depth of the secondary eclipse in these two bands we can place constraints on the planet’s atmospheric pressure–temperature profile and chemistry. We measure secondary eclipse de...
متن کاملKs-band secondary eclipses of WASP-19b and WASP-43b with the Anglo-Australian Telescope
We report new Ks-band secondary eclipse observations for the hot-Jupiters WASP-19b and WASP-43b. Using the IRIS2 infrared camera on the Anglo-Australian Telescope (AAT), we measured significant secondary eclipses for both planets, with depths of 0.287+0.020 −0.020 per cent and 0.181+0.027 −0.027 per cent for WASP-19b and WASP-43b, respectively. We compare the observations to atmosphere models f...
متن کاملProbing the extreme planetary atmosphere of WASP-12b
We report near-infrared measurements of the terminator region transmission spectrum and dayside emission spectrum of the exoplanet WASP-12b obtained using the HST WFC3 instrument. The disk-average dayside brightness temperature averages about 2900 K, peaking to 3200 K around 1.46 μm. Both the dayside and terminator region spectra can be explained in terms of opacity due to the metal hydrides Cr...
