Milky Way的化学动力学和椎间盘形成史：来自RAVE和Gaia-ESO调查的见解
Chemodynamics of the Milky Way and disc formation history: insight from the RAVE and Gaia-ESO surveys
摘要：
多目标摄谱仪为分析银河系老恒星的化学动力学性质打开了一扇新的窗口。这些分析使我们能够追溯影响银河系演化的内部机制和外部因素，从而了解星系演化的基本方面。在这里，我们提出了最近的结果，从径向速度实验（RAVE）和盖亚-ESO调查。这些巡天以不同的方式探索银河系的性质，包括样本大小和选择、星等范围和光谱分辨率。在这里，我们集中在（i）第一次直接检测的证据径向迁移薄盘内，提供洞察历史的银河系的螺旋结构，和（ii）的化学动力学特征的金属弱厚和薄盘，化学动力学模型仍然有困难在复制。
英文摘要：
Multi-object spectrographs have opened a new window on the analyses of the chemo-dynamical properties of old Milky Way stars. These analyses allow us to trace back the internal mechanisms and the external factors that have influenced the evolution of our Galaxy, and therefore understand fundamental aspects of galaxy evolution in general. Here, we present recent results from the RAdial Velocity Experiment (RAVE) and the Gaia-ESO survey. These surveys explore the Milky Way properties in different ways, in terms of sample size and selection, magnitude range, and spectral resolution. We focus here on (i) the first direct detection of evidence for radial migration within the thin disc, providing insight into the history of spiral structure of the Milky Way, and (ii) the chemo-dynamical characterisation of the metal-weak thick and thin discs, for which chemo-dynamical models still have difficulties in reproducing.
