Correlation between the two-armed $V_{R}$ spiral in the $Z$ -- $V_{Z}$ plane and moving groups

Yan Xu, Chao Liu, Chengdong Li +5

We use a cross-matched sample of 3.7 million stars from Gaia DR3 and LAMOST DR7 to investigate the velocity substructures in the Milky Way disk. The median radial velocity $V_{R}$ as…

The multiple corrugations in the Galactic disk derived from the LAMOST and Gaia survey data

Jifei Wang, Zhuohan Li, Chengdong Li +6

Large spectroscopic and astrometric surveys have revealed complex wave-like features in the Milky Way disk, suggesting that its kinematic and chemical structures are shaped by time…

Mapping the Milky Way with Gaia Bp/Rp spectra-IV: the broken and asymmetric density profile of the stellar disk traced by a large sample of red clumps

Wenbo Wu, Yuqin Chen, Jianhui Lian +10

This study explores the density profile of the stellar disk, radially and azimuthally, based on approximately 8.4 million red clump stars selected from Gaia Bp/Rp spectra. After co…
