A possible signature of non-uniform be-α relationships for the galaxy.

TAN K. and ZHAO G.

Abstract (from CDS):

Most of the previous studies on beryllium abundances in metal-poor stars have taken different Galactic populations as a whole when investigating the production and evolution of Be. In this Letter, we report on the detection of systematic differences in [α/H]-A(Be) relationships between the low- and high-α stars which were identified by previous works. We remind that one should be more careful in investigating the Galactic evolution of Be with a sample comprising different Galactic populations, because such a mixed sample may lead to inaccurate Be-Fe/Be-O relationships.
