The R-Process Alliance: a comprehensive abundance analysis of HD 222925, a metal-poor star with an extreme R-process enhancement of [Eu/H] = −0.14*
We present a detailed abundance analysis of the bright (V = 9.02), metal-poor ([Fe/H] = -1.47 ± 0.08) field red horizontal-branch star HD 222925, which was observed as part of an ongoing survey by the R-Process Alliance. We calculate stellar parameters and derive abundances for 46 elements based on...
