Exploring the ex-situ components within Gaia DR3

Zhuohan Li, Gang Zhao, Ruizhi Zhang +3

The presence of Gaia DR3 provides a large sample of stars with complete 6D information, offering a fertile ground for the exploration of stellar objects that were accreted to the M…

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…

A 3D Chemodynamical Census of Inner-Galaxy Metal-poor Giants to [Fe/H]~-3.5

Shenglan Sun, Yang Huang, Fangzhou Jiang +8

The earliest assembly of the Milky Way remains poorly understood, yet the spatial, chemical, and kinematic properties of its most metal-poor stars provide a unique fossil record of…

Estimating accretion times of halo substructures in the Milky Way

Hefan Li, Masashi Chiba, Xiang-Xiang Xue +1

To unravel the formation history of the Milky Way, we estimate the accretion times of six phase-space substructures in the stellar halo, using the orbital frequencies toward two sp…

Mapping the Milky Way with Gaia Bp/Rp spectra II: The inner stellar halo traced by a large sample of blue horizontal branch stars

Wenbo Wu, Xianhao Ye, C. Allende Prieto +7

We selected BHB stars based on synthetic photometry and stellar atmosphere parameters inferred from Gaia Bp/Rp spectra. We generated the synthetic SDSS broad-band and Pristin…

Identification of OB associations using the LAMOST-Gaia OB star sample

Zhicun Liu, Xiao-Long Wang, Wenyuan Cui +7

OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution, an…
