Diagonal Ridge pattern of different age populations found in Gaia DR2 with LAMOST Main-Sequence-Turn-Off and OB type Stars
H. -F. Wang, Y. Huang, H. -W. Zhang +5
We revisit the diagonal ridge feature (diagonal distributions in the plane) found in and present timing analysis for it between Galactocentric distances of …

Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: III: A new velocity substructure and time stamps of the Galactic disk asymmetry in the disk between 1215 \,kpc
H. -F. Wang, J. L. Carlin, Y. Huang +11
We investigate the three-dimensional asymmetrical kinematics and present time stamps of the Milky Way disk between Galactocentric distances of and 15 \,kpc, using red clump…

Disk stars in the Milky Way detected beyond 25 kpc from its center
M. Lopez-Corredoira, C. Allende Prieto, F. Garzon +3
CONTEXT. The maximum size of the Galactic stellar disk is not yet known. Some studies have suggested an abrupt drop-off of the stellar density of the disk at Galactocentric distanc…
