The R-process alliance: discovery of the first metal-poor star with a combined r- and s-process element signature

We present a high-resolution (R ∼ 35,000), high signal-to-noise ratio (S/N > 200) Magellan/MIKE spectrum of the star RAVE J094921.8-161722, a bright (V = 11.3) metal-poor red giant star with [Fe/H] = -2.2, identified as a carbon-enhanced metal-poor (CEMP) star from the RAVE survey. We report its...
