The beryllium abundance in the very metal-poor halo star G64-12 from VLT/UVES observations
We report on a newspectroscopic analysis of the very metal deficient star G64–12 ([Fe/H]=−3.3), aimed at determining, for the first time, its beryllium content. The spectra were observed during the Science Verification of UVES, the ESO VLT Ultraviolet and Visible Echelle Spectrograph. The high resolution (~48000) and high S/N (~130 per pixel) achieved at the wavelengths of the Be ii resonance doublet allowed an accurate determination of its abundance: log N(Be/H) = −13.10 ± 0.15 dex. The Be...[Show more]
