Detection of a Noble Gas Molecular Ion, {36}ArH^+, in the Crab Nebula
M. J. Barlow, B. M. Swinyard, P. J. Owen +9
Noble gas molecules have not hitherto been detected in space. From spectra obtained with the Herschel Space Observatory, we report the detection of emission in the 617.5 GHz and 12…
Gas signatures of Herbig Ae/Be disks probed with Herschel SPIRE spectroscopy
Matthijs H. D. van der Wiel, David A. Naylor, Giambattista Aresu +1
Herbig Ae/Be objects, like their lower mass counterparts T Tauri stars, are seen to form a stable circumstellar disk which is initially gas-rich and could ultimately form a planeta…
Herschel SPIRE and PACS observations of the red supergiant VY CMa: analysis of the molecular line spectra
Mikako Matsuura, J. A. Yates, M. J. Barlow +10
We present an analysis of the far-infrared and submillimetre molecular emission line spectrum of the luminous M-supergiant VY CMa, observed with the SPIRE and PACS spectrometers ab…
Herschel observations of the Sgr B2 cores: Hydrides, warm CO, and cold dust
M. Etxaluze, J. R. Goicoechea, J. Cernicharo +6
Sagittarius B2 (Sgr B2) is one of the most massive and luminous star-forming regions in the Galaxy and shows chemical and physical conditions similar to those in distant extragalac…
Far-Infrared Spectroscopy of the Galactic Center. Hot Molecular Gas: Shocks versus Radiation near SgrA*
Javier R. Goicoechea, M. Etxaluze, J. Cernicharo +10
We present a 52-671um spectral scan toward SgrA* taken with the PACS and SPIRE spectrometers onboard Herschel. The achieved angular resolution allows us to separate, for the first…
The HIFI spectral survey of AFGL2591 (CHESS). I. Highly excited linear rotor molecules in the high-mass protostellar envelope
M. H. D. van der Wiel, L. Pagani, F. F. S. van der Tak +2
We aim to reveal the gas energetics in the circumstellar environment of the prototypical high-mass protostellar object AFGL2591 using space-based far-infrared observations of linea…
