Subaru/HDS Study of the Extremely Metal-poor Star CS 29498-043: Abundance Analysis Details and Comparison with Other Carbon-rich Objects
We report on the details of an abundance study using the Subaru Telescope High Dispersion Spectrograph for the extremely metal-poor ([Fe/H] = -3.75) star CS 29498-043, whose overabundances of C, N, Mg, and Si were reported in our previous work. The effect of the large overabundance of Mg found in this object on the stellar atmosphere is included in the abundance analysis. We also performed a similar analysis for the other eight carbon-rich, metal-poor (-2.7 < [Fe/H] < -1.9) stars with excesses...[Show more]
