Ba-enhanced Dwarf and Subgiant Stars in the LAMOST Galactic Surveys

Ba-enhanced stars are interesting probes of stellar astrophysics and Galactic formation history. In this work, we investigate the chemistry and kinematics of a large sample of Ba-enhanced ([Ba/Fe]>1.0) dwarf and subgiant stars with 5000 < T _eff < 6700 K from LAMOST. We find that both stellar intern...
