The Origin of Water Vapor and Carbon Dioxide in Jupiter's Stratosphere
Lellouch, E.; Encrenaz, T.; Feuchtgruber, H. +6 more
Observations of H 2O rotational lines from the Infrared Space Observatory (ISO) and the Submillimeter Wave Astronomy Satellite (SWAS) and of the CO 2 ν 2 band by ISO are analyzed jointly to determine the origin of water vapor and carbon dioxide in Jupiter's stratosphere. Simultaneous modelling of ISO/LWS and ISO/SW…
The Nucleus of Comet 22P/Kopff and Its Inner Coma
Jorda, L.; Lamy, P. L.; A'Hearn, M. F. +3 more
We report the detection of the nucleus of Comet 22P/Kopff with the Planetary Camera of the Hubble Space Telescope (HST) and with the Infrared Camera of the Infrared Space Observatory (ISOCAM). The HST observations were performed on 18 July 1996, 16 days after its perihelion passage of 2 July 1996, when it was at Rh=1.59 AU from the Sun …
10 Hygiea: ISO Infrared Observations
Barucci, M. A.; Morris, P.; Crovisier, J. +10 more
Observations of emissivity features of 10 Hygiea have been made for the first time in the relatively unexplored thermal-infrared wavelength region with the ISO (Infrared Space Observatory) satellite. Spectrophotomer (PHT-S) and short wavelength spectrometer (SWS) spectra of 10 Hygiea, obtained at 5.8-11.6 and 7-45 µm, respectively, are prese…
