The barium overabundances observed at the surface of barium stars most likely 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.
