Scientific paper

It is shown that the emission band observed in the interval from 10 to 13 microns in the spectra of some carbon stars could arise from simple hydrocarbon molecules, especially the alkenes. These molecules could be present in circumstellar dust shells which are responsible for the 1000-K black-body excess observed for these stars, and the emission band is produced by collisional excitation.
