OH far-infrared emission from low- and intermediate-mass protostars surveyed with Herschel-PACS
S. F. Wampfler, S. Bruderer, A. Karska +10
OH is a key species in the water chemistry of star-forming regions, because its presence is tightly related to the formation and destruction of water. This paper presents OH observ…
ALMA CO J=6-5 observations of IRAS16293-2422: Shocks and entrainment
L. E. Kristensen, P. D. Klaassen, J. C. Mottram +2
Observations of higher-excited transitions of abundant molecules such as CO are important for determining where energy in the form of shocks is fed back into the parental envelope…
Evidence for CO shock excitation in NGC 6240 from Herschel SPIRE spectroscopy
R. Meijerink, L. E. Kristensen, A. Weiss +28
We present Herschel SPIRE FTS spectroscopy of the nearby luminous infrared galaxy NGC 6240. In total 20 lines are detected, including CO J=4-3 through J=13-12, 6 H2O rotational lin…
Mapping water in protostellar outflows with Herschel: PACS and HIFI observations of L1448-C
B. Nisini, G. Santangelo, S. Antoniucci +13
We investigate on the spatial and velocity distribution of H2O along the L1448 outflow, its relationship with other tracers, and its abundance variations, using maps of the o-H2O 1…
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…
First detection of water vapor in a pre-stellar core
Paola Caselli, Eric Keto, Edwin A. Bergin +11
Water is a crucial molecule in molecular astrophysics as it controls much of the gas/grain chemistry, including the formation and evolution of more complex organic molecules in ice…
The massive protostar W43-MM1 as seen by Herschel-HIFI water spectra: high turbulence and accretion luminosity
F. Herpin, L. Chavarria, F. van der Tak +7
We present Herschel/HIFI observations of fourteen water lines in W43-MM1, a massive protostellar object in the luminous star cluster-forming region W43. We analyze the gas dynamics…
Water in star-forming regions with Herschel (WISH): II. Evolution of 557 GHz 110-101 emission in low-mass protostars
L. E. Kristensen, E. F. van Dishoeck, E. A. Bergin +22
(Abridged) Water is a key tracer of dynamics and chemistry in low-mass protostars, but spectrally resolved observations have so far been limited in sensitivity and angular resoluti…
APEX-CHAMP+ high-J CO observations of low-mass young stellar objects: III. NGC 1333 IRAS 4A/4B envelope, outflow and UV heating
Umut A. Yıldız, Lars E. Kristensen, Ewine F. van Dishoeck +5
NGC 1333 IRAS 4A and IRAS 4B sources are among the best studied Stage 0 low-mass protostars which are driving prominent bipolar outflows. Most studies have so far concentrated on t…
The abundance of C18O and HDO in the envelope and hot core of the intermediate mass protostar NGC 7129 FIRS 2
A. Fuente, P. Caselli, C. McCoey +11
NGC 7129 FIRS 2 is a young intermediate-mass (IM) protostar, which is associated with two energetic bipolar outflows and displays clear signs of the presence of a hot core. It has…
