dc.description.abstract | We report the detection of the eclipse of the very hot Jupiter WASP-12b via z
-band time-series photometry obtained
with the 3.5 m Astrophysical Research Consortium telescope at Apache Point Observatory. We measure
a decrease in flux of 0.082% ± 0.015% during the passage of the planet behind the star. That planetary flux is
equally well reproduced by atmospheric models with and without extra absorbers, and blackbody models with
f 0.585 ± 0.080. It is therefore necessary to measure the planet at other wavelengths to further constrain its
atmospheric properties. The eclipse appears centered at phase φ = 0.5100+0.0072
−0.0061, consistent with an orbital eccentricity
of |e cos ω| = 0.016+0.011
−0.009 (see note at the end of Section 4). If the orbit of the planet is indeed eccentric, the
large radius of WASP-12b can be explained by tidal heating. | en_GB |
