A Ground‐based Search for Thermal Emission from the Exoplanet
Eclipsing planetary systems give us an important window on extrasolar planet atmospheres. By measuring the depth of the secondary eclipse, when the planet moves behind the star, we can estimate the strength of the thermal emission from the day side of the planet. Obtaining a ground-based detection of one of these eclipses has proven to be a significant challenge, as time-dependent variations in...
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...

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 کاملThermal Emission from Transiting Very-Hot Jupiters: Prospects for Ground-based Detection at Optical Wavelengths
Very hot Jupiters (VHJs) are defined as Jupiter-mass extrasolar planets with orbital periods shorter than three days. For low albedos the effective temperatures of irradiated VHJs can reach 2500–3000 K. Thermal emission from VHJs is therefore potentially strong at optical wavelengths. We explore the prospects of detecting optical-wavelength thermal emission during secondary eclipse with existin...
