Abstract

Accretion of interstellar material onto the metal-deficient halo stars that plunge through the disk is expected to mask the earlier production of the light elements in the big-bang nucleosynthesis. We propose a method to distinguish the primordial yield from that accreted in the secondary intragalactic motion of the stars by the use of heavy r- and s-process elements in these stars.
