Abundances of Extremely Metal-Poor Star Candidates
We present chemical abundances for 110 stars identified in objective-prism surveys as candidates to be very metal-poor. The abundances are derived from high S/N, intermediate-resolution spectra obtained with the Keck Observatory Echelle Spectrometer and Imager. An additional 25 stars with well-determined abundances ranging from [Fe/H]= −1.5 and −3.2 were observed and the results used to help ca...
متن کاملStar formation in metal-poor gas clouds
Observations of molecular clouds in metal-poor environments typically find that they have much higher star formation rates than one would expect based on their observed CO luminosities and the molecular gas masses that are inferred from them. This finding can be understood if one assumes that the conversion factor between CO luminosity and H2 mass is much larger in these low-metallicity systems...
متن کاملChemical Abundance Analysis of the Extremely Metal-poor Star
We present a detailed chemical abundance analysis of HE 1300+0157, a subgiant with [Fe/H] = −3.9. From a high-resolution, high-S/N Subaru/HDS spectrum we find the star to be enriched in C ([C/Fe]1D ∼ +1.4) and O ([O/Fe]1D ∼ +1.8). With the exception of these species, HE 1300+0157 exhibits an elemental abundance pattern similar to that found in many other very and extremely metal-poor stars. The...
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 کاملA New Type of Extremely Metal Poor Star
We present an abundance analysis for the extremely metal poor star HE1424−0241 based on high dispersion spectra from HIRES at Keck. This star is a giant on the lower red giant branch with [Fe/H] ∼ −4.0 dex. Relative to Fe, HE1424−0241 has normal Mg, but it shows a very large deficiency of Si, with ǫ(Si)/ǫ(Fe) ∼ 1/10 and ǫ(Si)/ǫ(Mg) ∼ 1/25 that of all previously known extremely metal poor giants...
