New beryllium observations in low-metallicity stars
We present observations of the Be II 313.0 nm 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≈ 8.6 kms−1 resolution. Abundances are derived bymeans of the synthetic spectra technique employing Kurucz (1993) atmospheric models, with enhanced α-elements and no overshooting...
متن کاملA New Population of Old Stars
We report the results of a coherent study of three chemically anomalous metal-poor ([Fe/H] ∼ –2) stars. These objects exhibit unusually low abundances of Mg, Si, Ca (α-elements) and Sr, Y, and Ba (neutron-capture elements). Our analyses confirm and expand upon earlier reports of atypical abundances in BD+80 245, G4-36, and CS22966-043. We also find that the latter two stars exhibit enhanced abu...
متن کاملEvents in Multimedia Electronic Chronicles (E-Chronicles)
The nature of information has changed significantly in the last two decades. Now information is multimedia, sensitive to its spatio-temporal roots, live, and dynamic. Current database and search technology is very limited in addressing organization, management, and access of emerging information systems. In this paper, we address some of the fundamental issues that must be addressed in general ...
متن کاملAtomic Diffusion and Mixing in Old Stars I. Vlt/flames-uves Observations of Stars in Ngc 6397
We present a homogeneous photometric and spectroscopic analysis of 18 stars along the evolutionary sequence of the metal-poor globular cluster NGC 6397 ([Fe/H]≈−2), from the main-sequence turnoff point to red giants below the bump. The spectroscopic stellar parameters, in particular stellarparameter differences between groups of stars, are in good agreement with broad-band and Strömgren photome...
متن کاملPlayer preferences among new and old violins.
Most violinists believe that instruments by Stradivari and Guarneri "del Gesu" are tonally superior to other violins--and to new violins in particular. Many mechanical and acoustical factors have been proposed to account for this superiority; however, the fundamental premise of tonal superiority has not yet been properly investigated. Player's judgments about a Stradivari's sound may be biased ...
