Revisiting the Radial Metallicity Gradient-Age Relation in the Milky Way's Thin and Thick Disks
Ao Chen, Juntai Shen, Chun Wang +1
Galactic disks typically exhibit a negative radial metallicity gradient, indicating faster enrichment in the inner regions. Recent studies report that this gradient becomes flatter…
A North-South Metallicity Asymmetry in the Outer Galactic disk -- Evidence for the Pericentric Passage of the Sagittarius Dwarf Galaxy
Chun Wang, Yang Huang, Timothy C. Beers +4
We present maps of the mean metallicity distributions on the Galactocentric -- plane at different azimuthal angles using red clump stars selected from the LAMOST and APOGEE s…
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…
The Stellar Disk Structure Rrevealed by the Mono-age Populations of the LAMOST Red Clump Sample
Zheng Yu, Bingqiu Chen, Jianhui Lian +2
Understanding the structure of the Galactic disk is crucial for understanding the formation and evolutionary history of the Milky Way. This study examines the structure of the Gala…
