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/…
The LAMOST Stellar Parameter Pipeline at Peking University --- LSP3
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We introduce the LAMOST Stellar Parameter Pipeline at Peking University --- LSP3, developed and implemented for the determinations of radial velocity and stellar atmosp…
Relative Flux Calibration of the LAMOST Spectroscopic Survey of the Galactic Anti-center
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +17
We have developed and implemented an iterative algorithm of flux calibration for the LAMOST Spectroscopic Survey of the Galactic anti-center (LSS-GAC). For a given LSS-GAC plate, t…
The velocity distribution in the solar neighbourhood from the LAMOST pilot survey
Qiran Xia, Chao Liu, Yan Xu +5
We use about 15,000 F/G nearby dwarf stars selected from the LAMOST pilot survey to map the U-V velocity distribution in the solar neighbourhood. An extreme deconvolution algorithm…
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…
Asteroseismic based estimation of the surface gravity for the LAMOST giant stars
Chao Liu, Min Fang, Yue Wu +7
Asteroseismology is one of the most accurate approaches to estimate the surface gravity of a star. However, most of the data from the current spectroscopic surveys do not have aste…
Fixing the Reference Frame for PPMXL Proper Motions Using Extragalactic Sources
Kathleen Grabowski, Jeffrey L. Carlin, Heidi Jo Newberg +14
We quantify and correct systematic errors in PPMXL proper motions using extragalactic sources from the first two LAMOST data releases and the Veron-Cetty & Veron Catalog of Quasars…
White dwarf-main sequence binaries from LAMOST: the DR1 catalogue
Juanjuan Ren, Alberto Rebassa-Mansergas, Ali Luo +6
Context. White dwarf-main sequence (WDMS) binaries are used to study several different important open problems in modern astrophysics. Aims. The Sloan Digital Sky Survey (SDSS) ide…
The Nearest High-Velocity Stars Revealed by LAMOST Data Release 1
Jing Zhong, Li Chen, Chao Liu +14
We report the discovery of 28 candidate high-velocity stars (HVSs) at heliocentric distances of less than 3 kpc, based on the Large Sky Area Multi-Object Fiber Spectroscopic Telesc…
Three Moving Groups Detected in the LAMOST DR1 Archive
Jingkun Zhao, Gang Zhao, Yuqin Chen +3
We analyze the kinematics of thick disk and halo stars observed by the Large sky Area Multi-Object Fiber Spectroscopic Telescope. We have constructed a sample of 7,993 F, G and K n…
A Search for Double-peaked narrow emission line Galaxies and AGNs in the LAMOST DR1
Zhi-Xin Shi, A-Li Luo, Georges Comte +15
LAMOST has released more than two million spectra, which provide the opportunity to search for double-peaked narrow emission line (NEL) galaxies and AGNs. The double-peaked narrow-…
The First Hypervelocity Star from the LAMOST Survey
Zheng Zheng, Jeffrey L. Carlin, Timothy C. Beers +10
We report the first hypervelocity star (HVS) discovered from the LAMOST spectroscopic survey. It is a B-type star with a heliocentric radial velocity about 620 km/s, which projects…
HST and LAMOST discover a dual active galactic nucleus in J0038+4128
Y. Huang, X. -W. Liu, H. -B. Yuan +6
We report the discovery of a kiloparsec-scale dual active galactic nucleus (AGN) in J0038+4128. From the Hubble Space Telescope (HST) Wide Field Planetary Camera (WFPC2) images, we…
