TL;DR: In this article, spectrally resolved observations of triatomic carbon (C-3) in several ro-vibrational transitions between the vibrational ground state and the low-energy nu(2) bending mode at frequencies between 1654-1897 GHz along the sight-lines to the submillimeter continuum sources W31C and W49N, using Herschel's HIFI instrument.
Journal ArticleDOI
The Slowly Expanding Envelope of CRL 618 Probed with HC3N Rotational Ladders
Juan R. Pardo,Juan R. Pardo,José Cernicharo,José Cernicharo,Javier R. Goicoechea,Thomas G. Phillips +5 more
TL;DR: In this article, the rotational lines of the C-rich protoplanetary nebula CRL 618 have been observed with the IRAM 30 m telescope toward this object, where lines from 15 different vibrational states (including the fundamental), with energies up to 1100 cm-1, have been detected for the main HC3N isotopomer.
Journal ArticleDOI

Claudia Comito,Peter Schilke,Maryvonne Gerin,Thomas G. Phillips,Jonas Zmuidzinas,Dariusz C. Lis +5 more
TL;DR: In this article, the authors reported the detection of the 894-GHz HDO(111-000) transition, observed in absorption against the background continuum emission of the SgrB2 cores M and N.
