Chemical and kinematic analysis of CN-strong Metal-poor Field Stars in LAMOST DR3
Baitian Tang, Chao Liu, J. G. Fernandez-Trincado +5
The large amount of chemical and kinematic information available in large spectroscopic surveys have inspired the search for chemically peculiar stars in the field. Though these me…
SDSS-IV MaStar -- A Large and Comprehensive Empirical Stellar Spectral Library: First Release
Renbin Yan, Yanping Chen, Daniel Lazarz +45
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength range of 3,622-10,354A…
Time stamps of vertical phase mixing in the Galactic disk from LAMOST-Gaia stars
Hai-Jun Tian, Chao Liu, Yue Wu +2
The perturbation mechanism of the Galactic disk has puzzled us for a long time. The imprints from perturbations provide important diagnostics on the disk formation and evolution. H…
The R-Process Alliance: 2MASS J09544277+5246414, the Most Actinide-Enhanced R-II Star Known
Erika M. Holmbeck, Timothy C. Beers, Ian U. Roederer +8
We report the discovery of a new actinide-boost star, 2MASS J09544277+5246414, originally identified as a very bright (V = 10.1), extremely metal-poor ([Fe/H] = -2.99) K giant in t…
Rotating halo traced by the K giant stars from LAMOST and Gaia
Hao Tian, Chao Liu, Yan Xu +1
With the help of Gaia DR2, we are able to obtain the full 6-D phase space information for stars from LAMOST DR5. With high precision of position, velocity, and metallicity, the rot…
Anisotropy of the Milky Way's stellar halo using K giants from LAMOST and
Sarah A. Bird, Xiang-Xiang Xue, Chao Liu +3
The anisotropy parameter characterizes the extent to which orbits in stellar systems are predominantly radial or tangential, and is likely to constrain, for the stellar halo of…
Mapping the Milky Way with LAMOST III: Complicated spatial structure in the outer disc
Hai-Feng Wang, Chao Liu, Yan Xu +2
We present {complexity} of the Galactic outer disc {by fitting the stellar volume densities of the red giant branch stars with a two-disc component model}. {The discs are confirmed…
Misclassified B stars in the Kepler field
Chunguang Zhang, Chao Liu, Yue Wu +7
Stellar fundamental parameters are important in the asteroseismic study of Kepler light curves. However, the most used estimates in the Kepler Input Catalog (KIC) are not accurate…
Carbon stars identified from LAMOST DR4 using Machine Learning
Yin-Bi Li, A-Li Luo, Chang-De Du +27
In this work, we present a catalog of 2651 carbon stars from the fourth Data Release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST). Using an effici…
