The Herschel-SPIRE instrument and its in-flight performance
The Spectral and Photometric Imaging REceiver (SPIRE), is the Herschel Space Observatory`s submillimetre camera and spectrometer. It contains a three-band imaging photometer operating at 250, 350 andExpand
The Spectrum of Comet Hale-Bopp (C/1995 O1) Observed with the Infrared Space Observatory at 2.9 Astronomical Units from the Sun
Several broad emission features observed in the 7- to 45-micrometer region suggest the presence of silicates, particularly magnesium-rich crystalline olivine, similar to those observed inThe dust envelopes of Vega-type stars. Expand
The deuterium abundance in Jupiter and Saturn from ISO-SWS observations
Observations with the Short Wavelength Spectrometer (SWS) onboard the Infrared Space Observatory (ISO) are used to determine the D/H ratio in Jupiter's and Saturn's atmospheres. The D/H ratio isExpand
Erratum: ``Vertical distribution of Titan's atmospheric neutral constituents''
The vertical distribution of Titan's neutral atmosphere compounds is calculated from a new photochemical model extending from 40 to 1432 km. This model makes use of many updated reaction rates, andExpand
Planck 2015 results. I. Overview of products and scientific results
The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14{\textasciitilde}May 2009and scanned the microwave andExpand
Photochemistry of Saturn's Atmosphere: I. Hydrocarbon Chemistry and Comparisons with ISO Observations
To investigate the details of hydrocarbon photochemistry on Saturn, we have developed a one-dimensional diurnally averaged model that couples hydrocarbon and oxygen photochemistry, molecular and eddyExpand
Rain, winds and haze during the Huygens probe's descent to Titan's surface
Spectra and high-resolution images obtained by the Huygens Probe Descent Imager/Spectral Radiometer instrument in Titan's atmosphere reveal the traces of once flowing liquid, and like Earth, the brighter highland regions show complex systems draining into flat, dark lowlands. Expand
External supply of oxygen to the atmospheres of the giant planets
The detection of gaseous H2O in the upper atmospheres of Saturn, Uranus and Neptune is reported by infrared spectroscopy and may help to constrain the injection rate and possible activity of distant icy objects in the Solar System. Expand
Subsurface properties and early activity of comet 67P/Churyumov-Gerasimenko
Subsurface temperatures showed seasonal and diurnal variations, which indicated that the submillimeter radiation originated at depths comparable to the diurnal thermal skin depth of comet 67P/Churyumov-Gerasimenko. Expand
Titan's atmosphere and hypothesized ocean: A reanalysis of the Voyager 1 radio-occultation and IRIS 7.7-μm data
Voyager1 radio-occultation refractivity profiles of Titan in the 0–200 km altitude range are reanalyzed in order to derive limiting profiles for the equatorial thermal structure, taking into accountExpand
