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.

Visual and infrared observations of late-type supergiants in the southern sky
Spectral types and photometry ranging from 0.4 to 18 microns are givenfor 54 late-type stars, including 21 supergiants. The infraredobservations of the supergiants confirm the dependence of the strengthof the 10-micron silicate emission feature on the spectral type andluminosity class of the star. The long-wavelength data are also used todetermine the interstellar extinction by fitting an appropriateblackbody to the infrared observations. The deviation from the blackbodyat the shorter wavelengths is then attributed to interstellar absorptionand absorption by TiO. This method is particularly useful when theshort-wavelength photometry is contaminated by a close companion. The Msupergiant AH Sco has excess radiation between 1.5 and 8 microns similarto the NML Tauri-type infrared stars. This excess energy resemblesfree-free emission.
