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…
A high resolution line survey of IRC+10216 with Herschel. First results: Detection of warm silicon dicarbide SiC2
J. Cernicharo, L. B. F. M. Waters, L. Decin +24
We present the first results of a high-spectral-resolution survey of the carbon-rich evolved star IRC+10216 that was carried out with the HIFI spectrometer onboard Herschel. This s…
Variations in H2O+/H2O ratios toward massive star-forming regions
F. Wyrowski, F. van der Tak, F. Herpin +63
Early results from the Herschel Space Observatory revealed the water cation H2O+ to be an abundant ingredient of the interstellar medium. Here we present new observations of the H2…
Water abundances in high-mass protostellar envelopes: Herschel observations with HIFI
M. Marseille, F. F. S. van der Tak, F. Herpin +4
We derive the dense core structure and the water abundance in four massive star-forming regions which may help understand the earliest stages of massive star formation. We present…
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…
Hydrides in Young Stellar Objects: Radiation tracers in a protostar-disk-outflow system
Arnold O. Benz, Simon Bruderer, Ewine F. van Dishoeck +2
Context: Hydrides of the most abundant heavier elements are fundamental molecules in cosmic chemistry. Some of them trace gas irradiated by UV or X-rays. Aims: We explore the abund…
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 vapor toward starless cores: the Herschel view
P. Caselli, E. Keto, L. Pagani +63
SWAS and Odin provided stringent upper limits on the gas phase water abundance of dark clouds (x(H2O) < 7x10^-9). We investigate the chemistry of water vapor in starless cores beyo…
