An Actinide-boost Star Discovered in the Gaia-Sausage-Enceladus
We report the discovery of an actinide-boost, very metal-poor ( $\left[{\rm{Fe}}/{\rm{H}}\right]=-2.38$ ), r -process-enhanced ( $\left[{\rm{Eu}}/{\rm{Fe}}\right]=0.80$ ) star, LAMOST J0804+5740, within the Gaia-Sausage-Enceladus (GSE). Based on the high-resolution ( R ∼ 36,000 and 60,000) and high...
