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…
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…
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…
Excitation and Abundance of C3 in star forming cores:Herschel/HIFI observations of the sight-lines to W31C and W49N
B. Mookerjea, T. Giesen, J. Stutzki +47
We present spectrally resolved observations of triatomic carbon (C3) in several ro-vibrational transitions between the vibrational ground state and the low-energy nu2 bending mode…
Detection of interstellar oxidaniumyl: abundant H2O+ towards the star-forming regions DR21, Sgr B2, and NGC6334
V. Ossenkopf, H. S. P. Müller, D. C. Lis +99
We identify a prominent absorption feature at 1115 GHz, detected in first HIFI spectra towards high-mass star-forming regions, and interpret its astrophysical origin. The character…
