The r-process Pattern of a Bright, Highly r -process-enhanced Metal-poor Halo Star at [Fe/H ] ~ -2

The r-process Pattern of a Bright, Highly r -process-enhanced Metal-poor Halo Star at [Fe/H ] ~ -2

All rights reserved.. A high-resolution spectroscopic analysis is presented for a new highly r-process-enhanced ([Eu/Fe] = 1.27, [Ba/Eu] = -0.65), very metal-poor ([Fe/H] = -2.09), retrograde halo star, RAVE J153830.9-180424, discovered as part of the R-Process Alliance survey. At V = 10.86, this is...
