Galactic Evolution of Beryllium and Oxygen
Published online by Cambridge University Press: 25 May 2016
Abstract
We discuss the early evolution of beryllium and oxygen in our Galaxy by comparing abundances of these elements for halo and disk metal-poor stars. Both, O and Be rise as we go progressively to more metal-rich stars, showing a slope 0.41 ± 0.09 ([Be/O] vs [Fe/H]) for stars with [Fe/H]≤ —1. This relationship provides an observational constraint to the actually proposed Galactic Cosmic Ray theories.
