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…
The Rotating Bulge and Halo in the Milky Way: Evidence of Angular Momentum Transferred from the Decelerating Bar
Zhuohan Li, Chengdong Li, Gang Zhao +2
Recent observations indicate that both the Milky Way bulge and inner halo exhibit angular momentum, although the origin and evolution of this prograde signature remain ambiguous. O…
Main-sequence Turnoff Stars as Probes of the Ancient Galactic Relic: Chemo-dynamical Analysis of a Pilot Sample
Renjing Xie, Haining Li, Ruizhi Zhang +5
The main-sequence turnoff (MSTO) stars well preserve the chemical properties where they were born, making them ideal tracers for studying the stellar population. We perform a detai…
The Shape and Mass of the Galactic Dark Matter Halo from the Axisymmetric Jeans Model
Lan Zhang, Xiang-Xiang Xue, Ling Zhu +8
We explore the density profile, shape, and virial mass of the Milky Way's dark matter halo using K giants (KG) from LAMOST and SDSS/SEGUE, as well as blue horizontal branch (BHB) s…
