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…
A study of three southern high-mass star-forming regions
C. Dedes, S. Leurini, F. Wyrowski +4
Based on color-selected IRAS point sources, we have started to conduct a survey of 47 high-mass star-forming regions in the southern hemisphere in 870um dust continuum and molecula…
Gas morphology and energetics at the surface of PDRs: new insights with Herschel observations of NGC 7023
C. Joblin, P. Pilleri, J. Montillaud +37
We investigate the physics and chemistry of the gas and dust in dense photon-dominated regions (PDRs), along with their dependence on the illuminating UV field. Using Herschel-HIFI…
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…
Hydrides in Young Stellar Objects: Radiation tracers in a protostar-disk-outflow system
Arnold O. Benz, Simon Bruderer, Ewine F. van Dishoeck +2
Context: Hydrides of the most abundant heavier elements are fundamental molecules in cosmic chemistry. Some of them trace gas irradiated by UV or X-rays. Aims: We explore the abund…
