Theoretical spectra of terrestrial exoplanet surfaces
We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si–O features in the thermal emission bands of 7–13μm and 15–25μm. The variation of brightness temperature due to the silicate features can be up to 20 K for an...
متن کاملSpectra as windows into exoplanet atmospheres.
Understanding a planet's atmosphere is a necessary condition for understanding not only the planet itself, but also its formation, structure, evolution, and habitability. This requirement puts a premium on obtaining spectra and developing credible interpretative tools with which to retrieve vital planetary information. However, for exoplanets, these twin goals are far from being realized. In th...
متن کاملExoplanet atmosphere. Thermal structure of an exoplanet atmosphere from phase-resolved emission spectroscopy.
Exoplanets that orbit close to their host stars are much more highly irradiated than their solar system counterparts. Understanding the thermal structures and appearances of these planets requires investigating how their atmospheres respond to such extreme stellar forcing. We present spectroscopic thermal emission measurements as a function of orbital phase ("phase-curve observations") for the ...
متن کاملTHE BROADBAND INFRARED EMISSION SPECTRUM OF THE EXOPLANET HD 189733b
We present Spitzer Space Telescope time series photometry of the exoplanet system HD 189733 spanning two times of secondary eclipse, when the planet passes out of view behind the parent star. We estimate the relative eclipse depth in 5 distinct bands and find the planet-to-star flux ratio to be 0.256±0.014% (3.6 μm), 0.214±0.020% (4.5 μm), 0.310 ± 0.034% (5.8 μm), 0.391 ± 0.022% (8.0 μm), and 0...
متن کاملThe thermal emission of the exoplanet WASP-3b
We report the detection of thermal emission from the transiting hot Jupiter WASP-3b at 3.6, 4.5 and 8.0μm using the Spitzer Space Telescope. We obtain planet-to-star flux ratios of 0.209+0.040 −0.028, 0.282 ± 0.012 and 0.328+0.086 −0.055 per cent at these wavelengths, respectively, implying infrared brightness temperatures of T3.6μm = 2280+210 −150 K, T4.5μm = 2400± 80K and T8.0μm = 2210+390 −2...
