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…
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…
LAMOST observations in the Kepler field. Analysis of the stellar parameters measured with the LASP based on the low-resolution spectra
Anbing Ren, Jianning Fu, Peter De Cat +12
All of the 14 subfields of the Kepler field have been observed at least once with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, Xinglong Observatory, China…
The LAMOST spectroscopic survey of star clusters in M31. II. Metallicities, ages and masses
Chen Bingqiu, Liu Xiaowei, Xiang Maosheng +14
We select from Paper I a sample of 306 massive star clusters observed with the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and…
A catalogue of early-type emission-line stars and Hα line profiles from LAMOST DR2
Wen Hou, ALi Luo, Jingyao Hu +9
We present a catalogue including 11,204 spectra for 10,436 early-type emission-line stars from LAMOST DR2, among which 9,752 early-type emission-line spectra are newly discovered.…
Calibration of LAMOST Stellar Surface Gravities Using the Kepler Asteroseismic Data
Liang Wang, Wei Wang, Yue Wu +7
Asteroseismology is a powerful tool to precisely determine the evolutionary status and fundamental properties of stars. With the unprecedented precision and nearly continuous photo…
Label Transfer from APOGEE to LAMOST: Precise Stellar Parameters for 450,000 LAMOST Giants
Anna Y. Q. Ho, Melissa K. Ness, David W. Hogg +6
In this era of large-scale stellar spectroscopic surveys, measurements of stellar attributes ("labels," i.e. parameters and abundances) must be made precise and consistent across s…
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…
An independent test of the photometric selection of white dwarf candidates using LAMOST DR3
N. P. Gentile Fusillo, A. Rebassa-Mansergas, B. T. Gänsicke +7
In Gentile Fusillo et al. (2015) we developed a selection method for white dwarf candidates which makes use of photometry, colours and proper motions to calculate a probability of…
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:…
Spectral classification of stars based on LAMOST spectra
Chao Liu, Wen-Yuan Cui, Bo Zhang +6
In this work, we select the high signal-to-noise ratio spectra of stars from the LAMOST data andmap theirMK classes to the spectral features. The equivalentwidths of the prominent…
