J/A+A/319/593 J/A+A/319/593 [Be] abundances in low-metallicity stars P Molaro P Bonifacio F Castelli L Pasquini Astron. Astrophys. 319 593 1997 1997A&A...319..593M Abundances Stars, metal-deficient cosmic rays cosmology: observations Galaxy: evolution stars: abundances stars: Population II We present observations of the Be II 313.0nm resonance doublet in 14 halo and old disk stars with metallicities ranging from [Fe/H]=-0.4 to =~-3.0 obtained with the CASPEC spectrograph of the ESO 3.6m telescope at a FWHM=~8.6km/s resolution. Abundances are derived by means of the synthetic spectra technique employing Kurucz (1993, CD-ROM 13 and CD-ROM 18) atmospheric models, with enhanced {alpha}-elements and no overshooting.
