Space velocities orbits in the Milky Way halo

We have compiled a sample of 699 stars from the recent literature with detailed chemical abundance information (spanning -4.2<~[Fe/H]<~+0.3), and we compute their space...本研究从近期发表的文献中汇编得到包含699颗恒星的样本，所有样本恒星均具备详细的化学丰度信息，其金属丰度（[Fe/H]）覆盖范围约为-4.2 < ~[Fe/H] < +0.3，本研究还对这些恒星的空间相关参数进行了计算
