Detection of OH and HO towards Orion~KL
H. Gupta, P. Rimmer, J. C. Pearson +76
We report observations of the reactive molecular ions OH, HO, and HO towards Orion KL with Herschel/HIFI. All three fine-structure transitions of OH…
The methanol lines and hot core of OMC2-FIR4, an intermediate-mass protostar, with Herschel-HIFI
M. Kama, C. Dominik, S. Maret +61
In contrast with numerous studies on the physical and chemical structure of low- and high-mass protostars, much less is known about their intermediate-mass counterparts, a class of…
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…
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…
First detection of ND in the solar-mass protostar IRAS16293-2422
A. Bacmann, E. Caux, P. Hily-Blant +64
In the past decade, much progress has been made in characterising the processes leading to the enhanced deuterium fractionation observed in the ISM and in particular in the cold, d…
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…
Herschel observations of EXtra-Ordinary Sources: the present and future of spectral surveys with Herschel/HIFI
E. A. Bergin, T. G. Phillips, C. Comito +56
We present initial results from the Herschel GT key program: Herschel observations of EXtra-Ordinary Sources (HEXOS) and outline the promise and potential of spectral surveys with…
Herschel observations of extra-ordinary sources: Detecting spiral arm clouds by CH absorption lines
S. -L. Qin, P. Schilke, C. Comito +67
We have observed CH absorption lines () against the continuum source Sgr~B2(M) using the \textit{Herschel}/HIFI instrument. With the high spectral…
Herschel/HIFI discovery of interstellar chloronium (HCl)
D. C. Lis, J. C. Pearson, D. A. Neufeld +102
We report the first detection of chloronium, HCl, in the interstellar medium, using the HIFI instrument aboard the \emph{Herschel} Space Observatory. The li…
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…
The CHESS chemical Herschel surveys of star forming regions: Peering into the protostellar shock L1157-B1. I. Shock chemical complexity
C. Codella, B. Lefloch, C. Ceccarelli +2
We present the first results of the unbiased survey of the L1157-B1 bow shock, obtained with HIFI in the framework of the key program Chemical Herschel surveys of star forming regi…
