A Catalogue of OB Stars from LAMOST Spectroscopic Survey
Zhicun Liu, Wenyuan Cui, Chao Liu +3
We present 22\,901 OB spectra of 16\,032 stars identified from LAMOST DR5 dataset. A larger sample of OB candidates are firstly selected from the distributions in the spectral line…
Ages and Masses of 0.64 million Red Giant Branch stars from the LAMOST Galactic Spectroscopic Survey
Yaqian Wu, Maosheng Xiang, Gang Zhao +13
We present a catalog of stellar age and mass estimates for a sample of 640\,986 red giant branch (RGB) stars of the Galactic disk from the LAMOST Galactic Spectroscopic Survey (DR4…
A new Hyper-Runaway star discovered from LAMOST and GAIA: ejected almost in the galactic rotation direction
Yin-Bi Li, A-Li Luo, Gang Zhao +11
In this paper, we report the discovery of a new late-B type unbound hyper-runaway star (LAMOST-HVS4) from the LAMOST spectroscopic surveys. According to its atmospheric parameters,…
Binary Star Fractions from the LAMOST DR4
Zhijia Tian, Xiaowei Liu, Haibo Yuan +17
Stellar systems composed of single, double, triple or high-order systems are rightfully regarded as the fundamental building blocks of the Milky Way. Binary stars play an important…
New Open Cluster Candidates Discovered in the XSTPS-GAC Survey
Jincheng Guo, Huawei Zhang, Huihua Zhang +11
The Xuyi Schmidt Telescope Photometric Survey of the Galactic Anti-center (XSTPS-GAC) is a photometric sky survey that covers nearly 6 000 deg^2 towards Galactic anti-center in g r…
Mass and Age of Red Giant Branch Stars Observed with LAMOST and \emph{Kepler}
Yaqian Wu, Maosheng Xiang, Shaolan Bi +13
Obtaining accurate and precise masses and ages for large numbers of giant stars is of great importance for unraveling the assemblage history of the Galaxy. In this paper, we estima…
Young and Intermediate-age Distance Indicators
Smitha Subramanian, Massimo Marengo, Anupam Bhardwaj +4
Distance measurements beyond geometrical and semi-geometrical methods, rely mainly on standard candles. As the name suggests, these objects have known luminosities by virtue of the…
Ages and masses of million Galactic disk main sequence turn-off and sub-giant stars from the LAMOST Galactic spectroscopic surveys
Maosheng Xiang, Xiaowei Liu, Jianrong Shi +10
We present estimates of stellar age and mass for 0.93 million Galactic disk main sequence turn-off and sub-giant stars from the LAMOST Galactic Spectroscopic Surveys. The ages and…
Estimating stellar atmospheric parameters, absolute magnitudes and elemental abundances from the LAMOST spectra with Kernel-based Principal Component Analysis
Maosheng Xiang, Xiaowei Liu, Jianrong Shi +16
Accurate determination of stellar atmospheric parameters and elemental abundances is crucial for Galactic archeology via large-scale spectroscopic surveys. In this paper, we estima…
Stellar Parameters of Main Sequence Turn-off Star Candidates Observed with the LAMOST and Kepler
Yaqian Wu, Maosheng Xiang, Xianfei Zhang +10
Main sequence turn-off (MSTO) stars have advantages as indicators of Galactic evolution since their ages could be robustly estimated from atmospheric parameters. Hundreds of thousa…
On the LSP3 estimates of surface gravity for LAMOST-Kepler stars with asteroseismic measurements
Juan-Juan Ren, Xiao-Wei Liu, Mao-Sheng Xiang +13
Asteroseismology allows for deriving precise values of surface gravity of stars. The accurate asteroseismic determinations now available for large number of stars in the Kepler fie…
Empirical metallicity-dependent calibrations of effective temperature against colours for dwarfs and giants based on interferometric data
Yang Huang, Xiao-Wei Liu, Hai-Bo Yuan +3
We present empirical metallicity-dependent calibrations of effective temperature against colours for dwarfs of luminosity classes IV and V and for giants of luminosity classes II a…
LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC): target selection and the first release of value-added catalogues
Haibo Yuan, Xiaowei Liu, Zhiying Huo +16
As a major component of the LAMOST Galactic surveys, the LAMOST Spectroscopic Survey of the Galactic Anti-centre (LSS-GAC) aims to survey a significant volume of the Galactic thin/…
Stellar loci II. a model-free estimate of the binary fraction for field FGK stars
Haibo Yuan, Xiaowei Liu, Maosheng Xiang +2
We propose a Stellar Locus OuTlier (SLOT) method to determine the binary fraction of main-sequence stars statistically. The method is sensitive to neither the period nor mass-ratio…
Stellar loci I. Metallicity dependence and intrinsic widths
Haibo Yuan, Xiaowei Liu, Maosheng Xiang +2
Stellar loci are widely used for selection of interesting outliers, reddening determinations, and calibrations. However, hitherto the dependence of stellar loci on metallicity has…
