A THICK, expanding envelope of dust and gas surrounds the unusual object IRC +10° 216. Microwave studies have identified numerous molecular constituents of the envelope1, and the thermal infrared spectrum indicates the probable presence of both silicon carbide and graphite in the form of dust grains (ref. 2, and M. P. Campbell, et al., unpublished). We report here the detection of acetylene, C2H2, in the infrared spectrum. Although acetylene is expected to be an important constituent of some… Expand
Infrared Spectroscopy of U Equulei’s Warm Circumstellar Gas
Medium- and high-resolution spectroscopy of U Equulei from 1 to 4 μm during 1997-2003 has revealed information about its unusual circumstellar envelope, observed previously at optical and radioExpand
Spectroscopic Studies of IRC+10216 and Similar Objects
Spectroscopy of circumstellar molecular species in the 2-14μm range provides evidence for a range of shell optical depths in the +10216 class of stars. In some cases a photospheric spectrum isExpand
Detection of infrared fluorescence of carbon dioxide in R Leonis with SOFIA/EXES.
The detection of hot CO2 in the O-rich AGB star R Leo is reported on based on high spectral resolution observations carried out with the Echelon-cross-Echelle Spectrograph mounted on the Stratospheric Observatory for Infrared Astronomy (SOFIA). Expand
We present the results of a search for the JK = 10→ 00 transition of PH3 (phosphine) at 267 GHz toward several circumstellar envelopes using the Arizona Radio Observatory 10 m Submillimeter TelescopeExpand

Absorption Cross Section of Gaseous Acetylene at 85 K in the Wavelength Range 110-155 nm
Absorption spectra and absorption cross sections of gaseous acetylene, C2H2, at 298 and 85?K were measured in the wavelength range 110-155?nm with a slit-jet system coupled to a synchrotron as aExpand
Microwave Spectra of Molecules of Astrophysical Interest. XX. Methane
The available data on methane are critically reviewed for information applicable to radio astronomy. Molecular data such as rotational constants, centrifugal distortion constants, and the distortionExpand
Radiative model for emission spectroscopy from optically thick laboratory acetylene samples at high temperature
Recently, a high temperature source has been used to produce high temperature emission spectra of acetylene in the 3 μm spectral range, under Doppler limited resolution, and the complete spectralExpand
Rotation-vibration spectra of linear acetylene for characterising astrophysical atmospheres
This thesis presents research carried out as part of the ExoMol project, towards calculating theoretical spectra for the main isotopologue of acetylene, C2H2, for use in characterising hot exoplanetExpand
