![]() The resolved spectral line profiles are used to separate and study various kinematic components. Selected frequency settings in the highest frequency HIFI bands (up to 1850 GHz) extend this range to 750 K for 12C 16O. Rotational spectral line signatures of CO species, HCO +, CS, HCN and HNC from a 490–1240 GHz survey with Herschel/HIFI, complemented by ground-based JCMT and IRAM 30 m spectra, cover transitions in the energy range ( E up/ k) between 5 K and ~300 K. ![]() We aim to reveal the gas energetics in the circumstellar environment of the prototypical high-mass protostellar object AFGL 2591. To probe this, space-based far-infrared observations are required.Īims. Molecular gas in the environment of massive protostellar objects, however, is known to reach temperatures of several hundred K. For these species, temperatures of ≲ 50 K are sufficient to produce emission lines that are observable from the ground at (sub)millimeter wavelengths. ![]() Linear rotor molecules such as CO, HCO + and HCN are important probes of star-forming gas. de l’Observatoire, 75014 Paris, Franceĥ Laboratoire d’Astrophysique de Grenoble, UMR 5571-CNRS, Université Joseph Fourier, Grenoble, FranceĬontext.
