Observations of Water Vapor Outflow from NML Cygnus

Viktor Zubko, Di Li, Tanya Lim +2

We report new observations of the far infrared and submillimeter water vapor emission of NML Cygnus based on data gathered with the Infrared Space Observatory and the Submillimeter…

W Hya : molecular inventory by ISO-SWS

K. Justtanont, T. de Jong, A. G. G. M. Tielens +2

Infrared spectroscopy is a powerful tool to probe the inventory of solid state and molecular species in circumstellar ejecta. Here we analyse the infrared spectrum of the Asymptoti…

Excitation of H_2 and HD in shocks and PDRs

F. Bertoldi, B. T. Draine, D. Rosenthal +5

Photodissociation regions (PDRs) and shocks give rise to conspicuous emission from rotationally and vibrationally excited molecular hydrogen. This line emission has now been studie…

ISO-SWS observations of pure rotational water absorption lines toward Orion-IRc2

C. M. Wright, E. F. van Dishoeck, J. H. Black +4

First detections of thermal water vapor absorption lines have been made toward Orion IRc2 using the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO…

Jupiter's hydrocarbons observed with ISO-SWS: vertical profiles of C2H6 and C2H2, detection of CH3C2H

T. Fouchet, E. Lellouch, B. Bezard +3

We have analysed the ISO-SWS spectrum of Jupiter in the 12-16 micron range, where several hydrocarbons exhibit rovibrational bands. Using temperature information from the methane a…
