The Herschel-HIFI view of mid-IR quiet massive protostellar objects
F. Herpin, L. Chavarria, T. Jacq +9
We present Herschel/HIFI observations (WISH KP) of 14 water lines in a small sample of galactic massive protostellar objects: NGC6334I(N), DR21(OH), IRAS16272-4837, and IRAS05358+3…
Herschel-HIFI observations of high-J CO lines in the NGC 1333 low-mass star-forming region
U. A. Yıldız, E. F. van Dishoeck, L. E. Kristensen +60
Herschel-HIFI observations of high-J lines (up to J_u=10) of 12CO, 13CO and C18O are presented toward three deeply embedded low-mass protostars, NGC 1333 IRAS 2A, IRAS 4A, and IRAS…
Ortho-to-para ratio of interstellar heavy water
C. Vastel, C. Ceccarelli, E. Caux +65
Despite the low elemental deuterium abundance in the Galaxy, enhanced molecular D/H ratios have been found in the environments of low-mass star forming regions, and in particular t…
Herschel-HIFI detections of hydrides towards AFGL 2591 (Envelope emission versus tenuous cloud absorption)
S. Bruderer, A. O. Benz, E. F. van Dishoeck +65
The Heterodyne Instrument for the Far Infrared (HIFI) onboard the Herschel Space Observatory allows the first observations of light diatomic molecules at high spectral resolution a…
Water in low-mass star-forming regions with Herschel: HIFI spectroscopy of NGC1333
L. E. Kristensen, R. Visser, E. F. van Dishoeck +64
'Water In Star-forming regions with Herschel' (WISH) is a key programme dedicated to studying the role of water and related species during the star-formation process and constraini…
Herschel observations of the hydroxyl radical (OH) in young stellar objects
S. F. Wampfler, G. J. Herczeg, S. Bruderer +58
Water in Star-forming regions with Herschel (WISH) is a Herschel Key Program investigating the water chemistry in young stellar objects (YSOs) during protostellar evolution. Hydrox…
Sensitive limits on the abundance of cold water vapor in the DM Tau protoplanetary disk
E. A. Bergin, M. R. Hogerheijde, C. Brinch +61
We performed a sensitive search for the ground-state emission lines of ortho- and para-water vapor in the DM Tau protoplanetary disk using the Herschel/HIFI instrument. No strong l…
Water in massive star-forming regions: HIFI observations of W3 IRS5
L. Chavarria, F. Herpin, T. Jacq +58
We present Herschel observations of the water molecule in the massive star-forming region W3 IRS5. The o-H17O 110-101, p-H18O 111-000, p-H2O 22 202-111, p-H2O 111-000, o-H2O 221-21…
Origin of the hot gas in low-mass protostars: Herschel-PACS spectroscopy of HH 46
T. A. van Kempen, L. E. Kristensen, G. J. Herczeg +62
'Water in Star-forming regions with Herschel' (WISH) is a Herschel Key Programme aimed at understanding the physical and chemical structure of young stellar objects (YSOs) with a f…
