R-Ferrite-type barium cobalt stannate, BaCo2Sn4O11
BaCo(2)Sn(4)O(11) is isotypic with R-ferrite, BaTi(2)Fe(4)O(11). The Co atoms fully occupy trigonal-bipyramidal sites () and are disordered with Sn atoms in octa-hedral sites (.2/m symmetry), as represented in the formula BaCoSn(2)(Co(0.34)Sn(0.66))(4)O(11). Ba atoms are situated in a 12-fold coordinated site ( symmetry).
متن کاملAbsolute magnitudes and kinematics of barium stars
The absolute magnitude of barium stars has been obtained from kinematical data using a new algorithm based on the maximum-likelihood principle. The method allows to separate a sample into groups characterized by different mean absolute magnitudes, kinematics and z-scale heights. It also takes into account, simultaneously, the censorship in the sample and the errors on the observables. The metho...
متن کاملBarium abundances in cool dwarf stars as a constraint to s- and r-process nucleosynthesis
We revise barium abundances in 11 cool stars with metallicities ranging from −2.65 to 0.05. The results are based on differential NLTE model atmosphere analyses of spectra that have a typical S/N of 200 and a resolution of 40000 or 60000. To minimize systematic errors of theoretical modeling and to be sure that elemental surface abundances are not contaminated by thermonuclear reaction products...
متن کاملAnalysis of 26 Barium Stars ⋆ , ⋆ ⋆ I . Abundances
Context. We present a detailed analysis of 26 barium stars, including dwarf barium stars, providing their atmospheric parameters (T eff , log g, [Fe/H], v t) and elemental abundances. Aims. We aim at deriving gravities and luminosity classes of the sample stars, in particular to confirm the existence of dwarf barium stars. Accurate abundances of chemical elements were derived. Abundance ratios ...
