THE 300 km s[superscript -1] STELLAR STREAM NEAR SEGUE 1: INSIGHTS FROM HIGH-RESOLUTION SPECTROSCOPY OF ITS BRIGHTEST STAR
We present a chemical abundance analysis of 300S-1, the brightest likely member star of the 300 km s[superscript -1] stream near the faint satellite galaxy Segue 1. From a high-resolution Magellan/MIKE spectrum, we determine a metallicity of [Fe/H] = -1.46 ± 0.05 ± 0.23 (random and systematic uncert...
