Exploring the total Galactic extinction with SDSS BHB stars
Hai-Jun Tian, Chao Liu, Jing-Yao Hu +2
Aims: We used 12,530 photometrically-selected blue horizontal branch (BHB) stars from the Sloan Digital Sky Survey (SDSS) to estimate the total extinction of the Milky Way at the h…
Substructure in bulk velocities of Milky Way disk stars
Jeffrey L. Carlin, James DeLaunay, Heidi Jo Newberg +11
We find that Galactic disk stars near the anticenter exhibit velocity asymmetries in both the Galactocentric radial and vertical components across the mid-plane as well as azimutha…
DA white dwarfs observed in LAMOST pilot survey
Yue-Yang Zhang, Li-Cai Deng, Chao Liu +14
A total of objects from LAMOST pilot survey have been publicly released. In this work, we present a catalog of DA white dwarfs from the entire pilot survey. We outlin…
Triggering star formation by both radiative and mechanical active galactic nucleus feedback
Chao Liu, Zhao-ming Gan, Fu-guo Xie
We perform two dimensional hydrodynamic numerical simulations to study the positive active galactic nucleus feedback which triggers, rather than suppresses, star formation. Recentl…
