The presence of methane in the atmosphere of an extrasolar planet
A near-infrared transmission spectrum of the planet HD 189733b that shows the presence of methane is reported, and a resolved water vapour band at 1.9 μm confirms the recent claim of water in this object.
The complex structure of the disk around HD 100546 - The inner few astronomical units
Disclosing the structure of disks surrounding Herbig AeBe stars is important to expand our understanding of the formation and early evolution of stars and planets. We aim at revealing the sub-AU disk…
MOLECULAR SIGNATURES IN THE NEAR-INFRARED DAYSIDE SPECTRUM OF HD 189733b
We have measured the dayside spectrum of HD 189733b between 1.5 and 2.5 μm using the NICMOS instrument on the Hubble Space Telescope. The emergent spectrum contains significant modulation, which we…
Observations of Transiting Exoplanets with the James Webb Space Telescope (JWST), Publications of the Astronomical Society of the Pacific (PASP), December 2014
This article summarizes a workshop held on March, 2014, on the potential of the James Webb Space Telescope (JWST) to revolutionize our knowledge of the physical properties of exoplanets through…
WATER, METHANE, AND CARBON DIOXIDE PRESENT IN THE DAYSIDE SPECTRUM OF THE EXOPLANET HD 209458b
Using the NICMOS instrument on the Hubble Space Telescope, we have measured the dayside spectrum of HD 209458b between 1.5 and 2.5 μm. The emergent spectrum is dominated by features due to the…
Probing the extreme planetary atmosphere of WASP-12b
The Mid-Infrared Spectrum of the Transiting Exoplanet HD 209458b
We report the spectroscopic detection of mid-infrared emission from the transiting exoplanet HD 209458b. Using archive data taken with the Spitzer IRS instrument, we have determined the spectrum of…
A ground-based near-infrared emission spectrum of the exoplanet HD 189733b
Ground-based observations of the dayside emission spectrum for HD’s 189733b suggest that non-LTE effects may need to be considered when interpreting measurements of strongly irradiated exoplanets.
Scientific motivation and technology requirements for the SPIRIT and SPECS far-infrared/submillimeter space interferometers
Far infrared interferometers in space would enable extraordinary measurements of the early universe, the formation of galaxies, stars, and planets, and would have great discovery potential. Since…
Ground-based detections of thermal emission from CoRoT-1b and WASP-12b
We report a new detection of the H-band thermal emission of CoRoT-1b and two confirmation detections of the Ks-band thermal emission of WASP-12b at secondary eclipses. The H-band measurement of…
