Neutral and Ionized Hydrides in Star-forming Regions -- Observations with Herschel/HIFI
Arnold O. Benz, Simon Bruderer, Ewine F. van Dishoeck +2
The cosmic abundance of hydrides depends critically on high-energy UV, X-ray, and particle irradiation. Here we study hydrides in star-forming regions where irradiation by the youn…
Tracing FUV Radiation in the Embedded Phase of Star Formation
Arnold O. Benz, Simon Bruderer, Ewine F. van Dishoeck +3
Molecules containing one or a few hydrogen atoms and a heavier atom (hydrides) have been predicted to trace FUV radiation. In some chemical models, FUV emission by the central obje…
Herschel-HIFI detections of hydrides towards AFGL 2591 (Envelope emission versus tenuous cloud absorption)
S. Bruderer, A. O. Benz, E. F. van Dishoeck +65
The Heterodyne Instrument for the Far Infrared (HIFI) onboard the Herschel Space Observatory allows the first observations of light diatomic molecules at high spectral resolution a…
Multidimensional Chemical Modeling. III. Abundance and excitation of diatomic hydrides
Simon Bruderer, Arnold O. Benz, P. Stäuber +1
The Herschel Space Observatory opens the sky for observations in the far infrared at high spectral and spatial resolution. A particular class of molecules will be directly observab…
