Spectroscopic Studies of Extremely Metal-poor Stars with the Subaru High-Dispersion Spectrograph. IV. The α-Element-Enhanced Metal-poor Star BS 16934-002
A detailed elemental abundance analysis has been carried out for the very metal-poor ([Fe/H] = -2.7) star BS 16934-002, which was identified in our previous work as a star exhibiting large overabundances of Mg and Sc. A comparison of the abundance pattern of this star with that of the well-studied metal-poor star HD 122563 indicates excesses of O, Na, Mg, Al, and Sc in BS 16934-002. Of particular interest, no excess of C or N is found in this object, in contrast to CS 22949-037 and CS...[Show more]
