Mixed chemistry phenomenon during late stages of stellar evolution.

SZCZERBA R., SCHMIDT M.R. and PULECKA M.

Abstract (from CDS):

We discuss phenomenon of simultaneous presence of O- and C-based material in the surroundings of evolutionary advanced stars. We concentrate on silicate carbon stars and present observations that directly confirm for them the binary model scenario. We discuss also the class of C-stars with OH emission detected, to which some [WR] planetary nebulae do belong.
