Ground-based detection of a vibration-rotation line of HD in Orion
T. R. Geballe, S. K. Ramsay Howat, R. Timmermann +2
The v =1-0 R(5) line of HD at 2.46um has been detected at the position of brightest line emission of shocked H2 in the Orion Molecular Cloud. The flux in this HD line, when compare…
Detection of a vibration-rotation emission line of hydrogen deuteride toward Orion Peak 1: excitation coupling of HD to H_2
S. K Ramsay Howat, R. Timmermann, T. R. Geballe +2
The 2.46um v=1-0 R(5) line of deuterated molecular hydrogen, HD, has been detected in the Orion Peak~1 shock emission region, at a surface brightness of (8.5 +/- 2.1) x 10^(-9) W m…
The aromatic infrared bands as seen by ISO-SWS: probing the PAH model
L. Verstraete, C. Pech, Claire Moutou +6
We discuss the Aromatic Infrared Band (AIB) profiles observed by ISO-SWS towards a number of bright interstellar regions where dense molecular gas is illuminated by stellar radiati…
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…
