Chemo-dynamics of outer halo dwarf stars

The low-metallicity, kinematically interesting dwarf stars studied by Stephens & Boesgaard (2002AJ....123.1647S, SB02) are re-examined using Gaia DR2 astrometry, and updated...本研究利用盖亚数据发布2（Gaia Data Release 2, DR2）的天体测量数据，对Stephens与Boesgaard（2002AJ....123.1647S，简称SB02）所研究的低金属丰度、运动学上值得关注的矮星进行了重新分析，并予以更新。
