Herschel observations of EXtra-Ordinary Sources (HEXOS): Observations of H2O and its isotopologues towards Orion KL

G. J. Melnick, V. Tolls, D. A. Neufeld +49

We report the detection of more than 48 velocity-resolved ground rotational state transitions of H2(16)O, H2(18)O, and H2(17)O - most for the first time - in both emission and abso…

Reversal of infall in SgrB2(M) revealed by Herschel/HIFI observations of HCN lines at THz frequencies

Rainer Rolffs, Peter Schilke, Claudia Comito +54

To investigate the accretion and feedback processes in massive star formation, we analyze the shapes of emission lines from hot molecular cores, whose asymmetries trace infall and…

Herschel observations of EXtra-Ordinary Sources: The Terahertz spectrum of Orion KL seen at high spectral resolution

N. R. Crockett, E. A. Bergin, S. Wang +60

We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (band 6b) and 1788.4 - 1906.8 GHz (band 7b) obtained using the HI…

Herschel/HIFI measurements of the ortho/para ratio in water towards Sagittarius B2(M) and W31C

D. C. Lis, T. G. Phillips, P. F. Goldsmith +74

We present Herschel/HIFI observations of the fundamental rotational transitions of ortho- and para-HO and HO in absorption towards Sagittarius~B2(M) and W31C. The…

Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sgr B2(M)

P. Schilke, C. Comito, H. S. P. Mueller +55

H2O+ has been observed in its ortho- and para- states toward the massive star forming core Sgr B2(M), located close to the Galactic center. The observations show absorption in all…

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…
