Low levels of methanol deuteration in the high-mass star-forming region NGC 6334I
Eva G. Bøgelund, Brett A. McGuire, Niels F. W. Ligterink +6
The abundance of deuterated molecules in a star-forming region is sensitive to the environment in which they are formed. Deuteration fractions therefore provide a powerful tool for…
Survey of cold water lines in protoplanetary disks: indications of systematic volatile depletion
Fujun Du, Edwin Anthony Bergin, Michiel Hogerheijde +11
We performed very deep searches for 2 ground-state water transitions in 13 protoplanetary disks with the HIFI instrument on-board the Herschel Space Observatory, with integration t…
Herschel/HIFI Spectral Mapping of C, CH, and CH in Orion BN/KL: The Prevailing Role of Ultraviolet Irradiation in CH Formation
Patrick W. Morris, Harshal Gupta, Zsofia Nagy +8
The CH ion is a key species in the initial steps of interstellar carbon chemistry. Its formation in diverse environments where it is observed is not well understood, however, b…
First detection of gas-phase ammonia in a planet-forming disk
Vachail N. Salinas, Michiel R. Hogerheijde, Edwin A. Bergin +10
Nitrogen chemistry in protoplanetary disks and the freeze-out on dust particles is key to understand the formation of nitrogen bearing species in early solar system analogs. So far…
Rotational spectroscopy as a tool to investigate interactions between vibrational polyads in symmetric top molecules: low-lying states of methyl cyanide, CHCN
Holger S. P. Müller, Linda R. Brown, Brian J. Drouin +6
Spectra of methyl cyanide were recorded to analyze interactions in low-lying vibrational states and to construct line lists for radio astronomical observations as well as for infra…
Herschel observations of EXtra-Ordinary Sources: Analysis of the HIFI 1.2 THz Wide Spectral Survey Toward Orion KL I. Methods
Nathan R. Crockett, Edwin A. Bergin, Justin L. Neill +19
We present a comprehensive analysis of a broad band spectral line survey of the Orion Kleinmann-Low nebula (Orion KL), one of the most chemically rich regions in the Galaxy, using…
