The R-Process Alliance: chemical abundances for a trio of R-process-enhanced stars -- one strong, one moderate, and one mild

We present detailed chemical abundances of three new bright (V ∼ 11), extremely metal-poor ([Fe/H] ∼-3.0), r-process-enhanced halo red giants based on high-resolution, high-S/N Magellan/MIKE spectra. We measured abundances for 20-25 neutron-capture elements in each of our stars. J1432-4125 is among...
