Detection of Lead in the Carbon-rich, Very Metal-poor Star LP 625-44: A Strong Constraint on s-Process Nucleosynthesis at Low Metallicity.
We report the detection of the Pb i lambda4057.8 line in the very metal-poor (&sqbl0;Fe&solm0;H&sqbr0;=-2.7), carbon-rich star, LP 625-44. We determine the abundance of Pb (&sqbl0;Pb&solm0;Fe&sqbr0;=2.65) and 15 other neutron-capture elements. The abundance pattern between Ba and Pb agrees well with a scaled solar system s-process component, while the lighter elements (Sr-Zr) are less abundant ...
متن کاملThe Chemical Composition of Carbon-Rich, Very Metal-Poor Stars: A New Class of Mildly Carbon-Rich Objects Without Excess of Neutron-Capture Elements
We report on an analysis of the chemical composition of five carbon-rich, very metalpoor stars based on high-resolution spectra. One star, CS 22948-027, exhibits very large overabundances of carbon, nitrogen, and the neutron-capture elements, as found in the previous study of Hill et al.. This result may be interpreted as a consequence of mass transfer from a binary companion that previously ev...
متن کاملChemical Composition of the Carbon-rich, Extremely Metal-Poor Star CS 29498–043: A New Class of Extremely Metal-Poor Stars with Excesses of Magnesium and Silicon
We analyze a high-resolution, high signal-to-noise spectrum of the carbon-rich, extremely metal-poor star CS 29498–043, obtained with the Subaru Telescope High Dispersion Spectrograph. We find its iron abundance is extremely low ([Fe/H] = −3.7), placing it among the few stars known with [Fe/H] ≤ −3.5, while Mg and Si are significantly overabundant ([Mg/Fe] = +1.8, and [Si/Fe] = +1.1) compared w...
متن کاملThe Chemical Composition of HE 1305+0132: A Carbon-Enhanced Metal-Poor Star with Enhanced Fluorine
The abundances of Fe, C, N, and Ba have been derived for the Carbon-Enhanced Metal-Poor star HE 1305+0132. The C and N abundances are typical of CEMP stars. The Ba abundance, derived for the first time for HE 1305+0132, is found to be enhanced relative to Fe, placing this star in the CEMP-s group. Combined with a previously derived highly enhanced abundance of F, the chemical composition of HE ...
متن کاملAnalysis of the carbon - rich very metal - poor dwarf G 77 - 61 ⋆
We present an analysis of the carbon dwarf G77-61, a known binary, based on high resolution Keck spectra. G77-61 has a very-low metallicity, although not as extreme as what was previously conjectured. This star is very carbon-enhanced, the spectra showing very strong CH, CN, and C2 bands of both 13C and 12C isotopes. Atomic lines are sparse, and often blended, but we were able to derive abundan...
