Barium stars revisited
(2010) International Conference on Binaries: In Celebration of Ron Webbink's 65th Birthday 1314. p.61-62- Abstract
The barium overabundances observed at the surface of barium stars originate from accretion long ago from the wind of a companion AGB star. However, this scenario cannot explain their high eccentricities and short orbital periods that have remained a mystery for decades. We investigate how kicks imparted to the white-dwarf at its birth or the presence of a circumbinary disk can solve this problem.
