LAMOST 1: A Disrupted Satellite in the Constellation Draco
John J. Vickers, Martin C. Smith, Yonghui Hou +2
Using LAMOST spectroscopic data, we find a strong signal of a comoving group of stars in the constellation of Draco. The group, observed near the apocenter of its orbit, is 2.6 kpc…
A sample of galaxy pairs identified from the LAMOST spectral survey and the Sloan Digital Sky Survey
Shiyin Shen, M. Argudo-Fernández, Li Chen +23
A small fraction() of SDSS main sample galaxies(MGs) have not been targeted with spectroscopy due to the the fiber collision effect. These galaxies have been compiled into t…
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…
Determining the local dark matter density with LAMOST data
Qiran Xia, Chao Liu, Shude Mao +7
Measurement of the local dark matter density plays an important role in both Galactic dynamics and dark matter direct detection experiments. However, the estimated values from prev…
The K giant stars from the LAMOST survey data II: the Hercules stream in radial migration
Chao Liu, Xiao-Yan Chen, Jun Yin +11
We estimate the age for the individual stars located at the lower part of the red giant branch from the LAMOST DR2 K giant sample. Taking into account the selection effects and the…
Validation of LAMOST Stellar Parameters with the PASTEL Catalog
Hua Gao, Huawei Zhang, Maosheng Xiang +8
Recently the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) published its first data release (DR1), which is ranked as the largest stellar spectra dataset in th…
The stellar kinematics in the solar neighborhood from LAMOST data
Hai-Jun Tian, Chao Liu, Jeffrey L. Carlin +6
We use about 200,000 FGK type main-sequence stars from the LAMOST DR1 data to map the local stellar kinematics. With the velocity de-projection technique, we are able to derive the…
Member candidates of the star clusters from LAMOST DR2 data
Bo Zhang, Xiao-Yan Chen, Chao Liu +10
In this work, we provide 2189 photometric- and kinematic-selected member candidates of 24 star clusters from the LAMOST DR2 catalog. We perform two-step membership identification:…
19 low mass hyper-velocity star candidates from the first data release of LAMOST survey
Yin-bi Li, A-Li Luo, Gang Zhao +12
Hyper-velocity stars are believed to be ejected out from the Galactic center through dynamical interactions between (binary) stars and the central massive black hole(s). In this pa…
A Sample of E+A Galaxy Candidates in LAMOST Data Released 2
Haifeng Yang, Ali Luo, Xiaoyan Chen +14
A sample of 70 E+A galaxies are selected from 37, 206 galaxies in the second data release (DR2) of Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) according to t…
On the metallicity gradients of the Galactic disk as revealed by LSS-GAC red clump stars
Yang Huang, Xiao-Wei Liu, Hua-Wei Zhang +10
Using a sample of over 70, 000 red clump (RC) stars with -% distance accuracy selected from the LAMOST Spectroscopic Survey of the Galactic Anti-center (LSS-GAC), we study t…
The LAMOST Survey of Background Quasars in the Vicinity Fields of the M 31 and M 33 - III. Results from the 2013 Regular Survey
Zhi-Ying Huo, Xiao-Wei Liu, Mao-Sheng Xiang +7
In this work, we report new quasars discovered in the vicinity fields of the Andromeda (M31) and Triangulum (M33) galaxies with the LAMOST (Large Sky Area Multi-Object Fiber Spectr…
The LAMOST Spectroscopic Survey of Globular Clusters in M 31 and M 33. I. Catalog and new identifications

We present a catalog of 908 objects observed with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and M33, targeted as globular…
Galactic Disk Bulk Motions as Revealed by the LSS-GAC DR2
Ning-Chen Sun, Xiao-Wei Liu, Yang Huang +10
We report a detailed investigation of the bulk motions of the nearby Galactic stellar disk, based on three samples selected from the LSS-GAC DR2: a global sample containing 0.57 mi…
The first symbiotic stars from the LAMOST survey
Jiao Li, Joanna Mikołajewska, Xue-Fei Chen +8
Symbiotic stars are interacting binary systems with the longest orbital periods. They are typically formed by a white dwarf, a red giant and a nebula. These objects are natural ast…
Spectral classification of stars based on LAMOST spectra
