We present spectroscopic evidence for an excess of the s-process element barium, in the rapidly rotating, K-dwarf component of the wide binary system 2REJ0357+283. The secondary star is a hot white dwarf (WD) and our result argues for a model where t... Read More about Excess barium in a K dwarf-white dwarf binary system..
