Sj. Chan, NEW SPECTRA OF CARBON STARS FROM THE IRAS LOW-RESOLUTION SPECTROMETER, Monthly Notices of the Royal Astronomical Society, 268(1), 1994, pp. 113-118
Low-resolution spectrometer (LRS) spectra of 152 IRAS CCGCS1 sources w
ith 12-mum fluxes of between 5 and 10 Jy are presented. This is part o
f an effort to extract spectra from the LRS 'raw data base' to search
for more carbon stars with silicate emission features. The new spectra
have been examined by eye and divided into six groups based on the cl
assification scheme of Volk & Cohen. Four new carbon stars with silica
te emission features (00519 + 5817, 19451 + 2856, 19583 - 0730 and 200
92 + 3557) are found. The LRS spectra of three other carbon stars (080
35 - 3837, 09083 - 5158 and 13182 - 6510) probably also contain silica
te emission features.
