Abstract. Barium stars are mostly G, K giants that are characterized by enhancement of heavy elements relative to Fe as well as enhanced CH, CN and C2 molecular bands. Observed enhancement in abundances of heavy elements in these objects are generally explained to be a result of mass transfer from a companion star that has undergone its second ascent of the giant branch, becoming an AGB star. Results from photometric and spectroscopic analysis for a sample of barium stars will be presented.
