Cosmological Insights into the Early Accretion of r -process-enhanced Stars. I. A Comprehensive Chemodynamical Analysis of LAMOST J1109+0754

This study presents a comprehensive chemodynamical analysis of LAMOST J1109+0754, a bright (V = 12.8), extremely metal-poor ([Fe/H] = -3.17) star, with a strong r-process enhancement ([Eu/Fe] = +0.94 ± 0.12). Our results are based on the 7D measurements supplied by Gaia and the chemical composition...
