Water in star-forming regions (WISH): Physics and chemistry from clouds to disks as probed by Herschel spectroscopy
E. F. van Dishoeck, L. E. Kristensen, the WISH team
(abridged) Data and results from the WISH key program are summarized, designed to provide a legacy data set to address its physics and chemistry. WISH targeted ~80 sources along th…
The ALMA-PILS survey: first detection of methyl isocyanide (CHNC) in a solar-type protostar
H. Calcutt, M. R. Fiechter, E. R. Willis +9
Methyl isocyanide (CHNC) is the isocyanide with the largest number of atoms confirmed in the interstellar medium (ISM), but it is not an abundant molecule, having only been det…
The ALMA-PILS survey: Complex nitriles towards IRAS 16293--2422
H. Calcutt, J. K. Jørgensen, H. S. P. Müller +8
Complex organic molecules are readily detected in the inner regions of the gaseous envelopes of forming protostars. In particular, molecules that contain nitrogen are interesting d…
The ALMA-PILS survey: Formaldehyde deuteration in warm gas on small scales toward IRAS 16293-2422 B
M. V. Persson, J. K. Jørgensen, H. S. P. Müller +7
[abridged] The enhanced degrees of deuterium fractionation observed in envelopes around protostars demonstrate the importance of chemistry at low temperatures, relevant in pre- and…
Origin of warm and hot gas emission from low-mass protostars: Herschel-HIFI observations of CO J=16-15. I. Line profiles, physical conditions, and H2O abundance
L. E. Kristensen, E. F. van Dishoeck, J. C. Mottram +18
(Abridged) Through spectrally unresolved observations of high-J CO transitions, Herschel-PACS has revealed large reservoirs of warm (300 K) and hot (700 K) molecular gas around low…
Challenging shock models with SOFIA OH observations in the high-mass star-forming region Cepheus A
A. Gusdorf, R. Guesten, K. M. Menten +13
OH is a key molecule in H2O chemistry, a valuable tool for probing physical conditions, and an important contributor to the cooling of shock regions. OH participates in the re-dist…
The complete far-infrared and submillimeter spectrum of the Class 0 protostar Serpens SMM1 obtained with Herschel. Characterizing UV-irradiated shocks heating and chemistry
Javier R. Goicoechea, J. Cernicharo, A. Karska +8
We present the first complete 55-671 um spectral scan of a low-mass Class 0 protostar (Serpens SMM1) taken with the PACS and SPIRE spectrometers on board Herschel. More than 145 li…
High-J CO emission in the Cepheus E protostellar outflow observed with SOFIA/GREAT
A. I. Gómez-Ruiz, A. Gusdorf, S. Leurini +6
We present and analyze two spectrally resolved high-J CO lines towards the molecular outflow Cep E, driven by an intermediate-mass class 0 protostar. Using the GREAT receiver on bo…
Water in star-forming regions with Herschel: highly excited molecular emission from the NGC 1333 IRAS 4B outflow
Gregory J. Herczeg, Agata Karska, Simon Bruderer +9
During the embedded phase of pre-main sequence stellar evolution, a disk forms from the dense envelope while an accretion-driven outflow carves out a cavity within the envelope. Hi…
Water in Star-Forming Regions with the Herschel Space Observatory (WISH): Overview of key program and first results
E. F. van Dishoeck, L. E. Kristensen, A. O. Benz +12
`Water In Star-forming regions with Herschel' (WISH) is a key program on the Herschel Space Observatory designed to probe the physical and chemical structure of young stellar objec…
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 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…
