Journal ArticleDOI
Detection of Methane in the Atmosphere of Mars
Vittorio Formisano,Sushil K. Atreya,Thérèse Encrenaz,Nikolai Ignatiev,Nikolai Ignatiev,Marco Giuranna +5 more
TL;DR: A detection of methane in the martian atmosphere by the Planetary Fourier Spectrometer onboard the Mars Express spacecraft is reported, and the global average methane mixing ratio is found to be 10 ± 5 parts per billion by volume.
Journal ArticleDOI
Titan’s atmosphere from ISO mid-infrared spectroscopy
Athena Coustenis,Alberto Salama,Benjamin L. Schulz,S. Ott,E. Lellouch,Thérèse Encrenaz,D. Gautier,Helmut Feuchtgruber +7 more
TL;DR: In this paper, the authors analyzed Titan observations performed by the Infrared Space Observatory (ISO) in the range 7-30 μm and obtained the monodeuterated methane-averaged abundance and retrieved a D/H isotopic ratio of 8.7−1.
Journal ArticleDOI
Hydrogen peroxide on Mars: evidence for spatial and seasonal variations
Thérèse Encrenaz,Bruno Bézard,Thomas K. Greathouse,Matthew J. Richter,John H. Lacy,Sushil K. Atreya,A. S. Wong,Sébastien Lebonnois,Franck Lefèvre,François Forget +9 more
TL;DR: Clancy et al. as discussed by the authors reported the detection of H2O2 on Mars in June 2003, and its mapping over the martian disk using the same technique, during the southern spring (Ls=206°) when the global water vapor abundance was ∼10 pr.
Journal ArticleDOI
Spectroscopy of planetary atmospheres in our Galaxy
TL;DR: In this article, the authors review the key achievements accomplished in the study of exoplanet atmospheres in the past ten years and discuss possible hurdles and the way to overcome those.
Journal ArticleDOI
ISO-SWS Observations of Jupiter: Measurement of the Ammonia Tropospheric Profile and of the 15N/14N Isotopic Ratio
Thierry Fouchet,Emmanuel Lellouch,Bruno Bézard,Thérèse Encrenaz,Pierre Drossart,Helmut Feuchtgruber,Thijs de Graauw +6 more
TL;DR: In this article, the results of the Infrared Space Observatory Short Wavelength Spectrometer (ISO-SWS) observations of Jupiter related to ammonia were presented, where the authors focused on two spectral regions; the first one (the 10-μm region), ranging from 9.5 to 11.5 μm, probes atmospheric levels between 1 and 0.2 bar, while the second one, ranging from 4.8 to 5.5μm, sounds the atmosphere between 8 and 2 bar.
