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…
Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: VIII: Mapping the kinematics of the Galactic disk using mono-age and mono-abundance stellar populations
Weixiang Sun, Yang Huang, Han Shen +5
We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a larg…
Precise Masses, Ages of ~1.0 million RGB and RC stars observed by the LAMOST
Chun Wang, Yang Huang, Yutao Zhou +1
We construct a catalogue of stellar masses and ages for 696,680 red giant branch (RGB) stars, 180,436 primary red clump (RC) stars, and 120,907 secondary RC stars selected from the…
