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…
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: 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 observations of high-J CO transitions in the protoplanetary nebula CRL618
V. Bujarrabal, J. Alcolea, R. Soria-Ruiz +25
We performed Herschel/HIFI observations of several CO lines in the far-infrared/sub-mm in the protoplanetary nebula CRL618. The high spectral resolution provided by HIFI allows mea…
Water content and wind acceleration in the envelope around the oxygen-rich AGB star IK Tau as seen by Herschel/HIFI
L. Decin, K. Justtanont, E. De Beck +4
During their asymptotic giant branch, evolution low-mass stars lose a significant fraction of their mass through an intense wind, enriching the interstellar medium with products of…
HIFI observations of warm gas in DR21: Shock versus radiative heating
V. Ossenkopf, M. Röllig, R. Simon +35
The molecular gas in the DR21 massive star formation region is known to be affected by the strong UV field from the central star cluster and by a fast outflow creating a bright sho…
