The 300 km s -1 stellar stream near Segue 1: Insights from high-resolution spectroscopy of its brightest star

Frebel, Anna; Lunnan, Ragnhild; Casey, Andrew; Norris, John; Wyse, Rosemary F G; Gilmore, Gerard


We present a chemical abundance analysis of 300S-1, the brightest likely member star of the 300 km s-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
