Tracing Cosmic-Rays and SNe with Be Abundances

We present the results of a new analysis of Be abundances in a large sample of stars, spanning the metallicity range -2.5 ≤ Fe/H] ≤ - 0.7. The observations were taken with the Ultraviolet and Visible Echelle Spectrograph (UVES) at the ESO Very Large Telescope (VLT). With this new set of high quality data we aim at further investigating the trend of Be with metallicity, the possible presence of dispersion, and their implications for cosmic-ray and supernovae physics. This revised version was published online in September 2006 with corrections to the Cover Date.
