  "abstract": "Observational manifestations of far evolved stars at the asymptotic giants branch and their nearest descendants are briefly considered. Main results of their chemical composition determinations based on long term high resolution spectroscopy at the 6-m telescope are also briefly summed up. A new kind of peculiarity of optical spectra is found and discussed: splitting or asymmetry of strongest absorptions in the optical spectra of selected post-AGB stars with envelopes and atmospheres enriched in carbon and s-process heavy metals.",
