On the radial metallicity gradient and radial migration effect of the Galactic disk

Yunpeng Jia, Yuqin Chen, Gang Zhao +4

We study the radial metallicity gradient $Δ [M / H] /Δ R_{g}$ as a function of [Mg/Fe] and $∣ Z ∣$ with the help of a guiding radius based on the Apache Point Observatory Galactic Evolution…

Anisotropy of the Milky Way's stellar halo using K giants from LAMOST and $G aia$

Sarah A. Bird, Xiang-Xiang Xue, Chao Liu +3

The anisotropy parameter $β$ characterizes the extent to which orbits in stellar systems are predominantly radial or tangential, and is likely to constrain, for the stellar halo of…
