摘要

我们引入了一种新的轨道叠加方法，旨在利用来自APOGEE DR17空间覆盖范围有限的分辨恒星群的6D相空间信息，重建整个银河系的恒星密度结构、运动学和化学丰度分布。

Rediscovering the Milky Way with an orbit superposition approach and APOGEE data

We introduce a novel orbit superposition method designed to reconstruct the stellar density structure, kinematics, and chemical abundance distribution of the entire Milky Way by leveraging 6D phase-space information from its resolved stellar populations, limited by the spatial coverage of APOGEE DR17.
