RAVE J203843.2-002333: The First Highly R-process-enhanced Star Identified in the RAVE Survey

We report the discovery of RAVE J203843.2-002333, a bright (V = 12.73), very metal-poor ([Fe/H] = -2.91), r-process-enhanced ([Ba/Eu] = +1.64 and = -0.81) star selected from the RAVE survey. This star was identified as a metal-poor candidate based on its medium-resolution (R ∼ 1600) spectrum obtaine...
