Classification and Identification of IRAS Sources with Low-Resolution Spectra IRAS low-resolution spectra were extracted for 11,224 IRAS sources.These spectra were classified into astrophysical classes, based on thepresence of emission and absorption features and on the shape of thecontinuum. Counterparts of these IRAS sources in existing optical andinfrared catalogs are identified, and their optical spectral types arelisted if they are known. The correlations between thephotospheric/optical and circumstellar/infrared classification arediscussed.
| Constraints on the molecular properties of interstellar X-ogen derived from radio observations Twenty-eight X-ogen emission sources at 89.189 GHz have been detectedand observed. Twenty of these are new X-ogen sources which also containother interstellar molecules. No infrared stars are found to be X-ogensources. A new rest frequency (89,188.65 MHz) is derived for X-ogen. Itis shown that X-ogen is not SiC, C2H, or any molecule withspin-doubling, hyperfine structure, or both.
