Heavy - element abundances in the CH / CN - strong very metal - poor stars CS 22948 - 27 and CS 29497 - 34 ?
We have carried out a new analysis of the very metalpoor CH/CN strong stars CS 22948-27 and CS 29497-34. In particular, the effective temperatures were recomputed by comparing newly obtained photometric data to colours derived from model atmospheres computed especially for these stars. Metallicities of [Fe/H] = −2.45 and −2.90 are found, respectively, for CS 22948-27 and CS 29497-34. The abunda...
متن کاملExtremely Metal-poor Stars. Ix. Cs 22949-037 and the Role of Hypernovae
We have obtained high-resolution spectra of the extremely metal-poor star CS 22949-037 ( ) [Fe/H] p 3.79 in the region of the ultraviolet NH bands at 3360–3370 Å, which confirm our earlier report that it exhibits extreme nitrogen enhancement. We find . The star is also known to have large relative overabundances, [N/Fe] p 2.3 0.4 of order 0.5–1 dex, of carbon and the a-elements. This abundance ...
متن کاملCS 30322 - 023 : an ultra metal - poor TP - AGB star ? ⋆
Context. The remarkable properties of CS 30322-023 became apparent during the course of a high-resolution spectroscopic study of a sample of 23 carbon-enhanced, metal-poor (CEMP) stars. Aims. This sample is studied in order to gain a better understanding of sand r-process nucleosynthesis at low metallicity, and to investigate the role of duplicity. Methods. High-resolution UVES spectra have bee...
متن کاملCS 22957 - 027 : a carbon - rich extremely - metal - poor star ?
We present a high-resolution spectroscopic analysis of the extremely-metal-poor star CS 22957-027, which Beers et al. (1992) noted to exhibit a rather strong G-band. For T eff = 4839 K, derived from broadband photometry, our analysis obtains log g= 2.25, and a very low metallicity of [Fe/H]=−3.43 ± 0.12. The carbon-to-iron ratio is found to be enhanced by ≈ 2 dex relative to the solar value, si...
متن کاملQuestion Analysis and Query Expansion in CS-CS IR4QA
This paper describes our work in NTCIR-7 on the subtask of simplified Chinese monolingual information retrieval for question answering (CS-CS IR4QA). Based on the observation that inappropriate key terms and term mismatch often result in depressed precision and impressive recall, we employ a special question analysis method extracting more appropriate key terms and apply the query expansion tec...
