J/A+A/319/593       [Be] abundances in low-metallicity stars (Molaro+ 1997)

New beryllium observations in low-metallicity stars Molaro P., Bonifacio P., Castelli F., Pasquini L. <Astron. Astrophys. 319, 593 (1997)> =1997A&A...319..593M (SIMBAD/NED BibCode)
ADC_Keywords: Stars, metal-deficient ; Abundances Keywords: stars: abundances - stars: Population II - Galaxy: evolution - cosmology: observation - ISM: cosmic rays Description: 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 α-elements and no overshooting. File Summary:
