The R-Process Alliance: The r-process Enhancement of Stars from Chemodynamically Tagged Groups in the Milky Way Halo

As part of the ongoing work of the R -Process Alliance (RPA), detailed abundance measurements of 29 heavy elements in three metal-poor stars, 2MASS J14592981−3852558, 2MASS J19445483−4039459, and 2MASS J15211026−0607566, are presented based on an analysis of high-resolution ( R  ∼ 80,000), high-sign...
