More (on) red giants with unusual dust shells.

Abstract (from CDS):

Twenty-four M- and MS-stars have been suggested in the literature to show the silicon carbide feature, indicative of a carbon-rich circumstellar shell. By cross-correlating the IRAS LRS atlas with Bidelman's compilation of spectral types for objects in the IRC survey, this sample is enlarged to 39 sources. By carefully examining the LRS spectra, it appears that only one source shows silicon carbide emission. However, there is doubt on the correct association of this IRC source with the IRAS source and on the spectral type of the IRC source. The remaining objects are shown to have no dust, featureless dust, to show the characteristic silicate feature at 18µm, or to display a broad feature from 10-14µm which is known from previous studies on the dust around M-stars. I conclude that based on the present sample there is no or weak evidence that silicon carbide dust forms in the shells around M- and MS-stars.
