Divergent Evolution of Radial Metallicity Gradients in the Thin and Thick Disks of the Milky Way
Weixiang Sun, Gaohuan Long, Hui Li +6
Using 200,388 red clump stars from LAMOST and APOGEE, we investigate the radial metallicity gradients of the Galactic disk as a function of vertical height and stellar age. The thi…

The Vertical Metallicity Gradient of the Galactic Disk for Mono-Age Stellar Populations in LAMOST
Gaohuan Long, Haibo Yuan, Shuai Xu +3
The vertical metallicity gradient of the Galactic disk offers valuable insights into the disk's formation and chemical evolution over time. We utilized the LAMOST-LRS young stellar…
