Newly identified carbon stars from sources with unusual IRAS low-resolution spectra.

CHEN P.S. and SHAN H.G.

Abstract (from CDS):

The 11.2 µm SiC feature in either emission or absorption in the infrared is an important indicator for identification of carbon stars. Sources whose infrared spectra are sorted in Group U of the Infrared Astronomical Satellite (IRAS) low-resolution spectrum (LRS) are good samples for finding objects with the 11.2 µm SiC feature. Therefore, we have carefully checked all spectra in Group U of the LRS. We have found 13 new objects, which probably have SiC emission, sometimes with unusually broad features, that are presumed to be carbon-rich objects. In addition, their evolutionary types are also estimated from IRAS and Two Micron All Sky Survey two-color diagrams. Besides finding 13 new carbon-rich objects, another important result in this paper is that four sources are estimated as new extreme carbon stars (ECSs) and five previously known carbon stars sorted in the Group U of the IRAS LRS are also estimated as ECSs.
