Discussion on candidates for the M stars with 11.2 µm SiC feature.

Abstract (from CDS):

The oxygen-rich stars with SiC emission features are unexpected according to the evolutionary theory in the late stage of stellar evolution. After the careful re-examination of such samples reported previously and searching for new samples, seven stars are found to be the candidates of the M stars with 11.2 mum SiC emission feature. However, with the IRAS low-resolution spectrum, the IRAS two colour diagram and other information, it is seen that no strong candidates for oxygen-rich AGB stars with carbon-rich circumstellar dust could be found so far.
