LAMOST Spectrograph Response Curves: Stability and Application to flux calibration
Bing Du, A-Li Luo, Zhong-Rui Bai +14
The task of flux calibration for LAMOST (Large sky Area Multi-Object Spectroscopic Telescope) spectra is difficult due to many factors. For example, the lack of standard stars, fla…
LAMOST Observations of Flaring M Dwarfs in the Kepler Field
H. -Y. Chang, Y. -H. Song, A. -L. Luo +7
A sample of the LAMOST spectra of the early type M0-M3 dwarfs is compared with the Kepler observations. It is found that M dwarfs with strong chromospheric emission in have l…
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…
Exoplanet Orbital Eccentricities Derived From LAMOST-Kepler Analysis
Ji-Wei Xie, Subo Dong, Zhaohuan Zhu +14
The nearly circular (mean eccentricity <e>~0.06) and coplanar (mean mutual inclination <i>~3 deg) orbits of the Solar System planets motivated Kant and Laplace to put forth the hyp…
Spectral Identification of the u-band Variable Sources in Two LAMOST fields
TianWen Cao, Ming Yang, Hong Wu +17
We selected 82 u-band variable objects based on the u-band photometry data from SCUSS and SDSS, in the field of LAMOST Complete Spectroscopic Survey of Pointing Area at Southern Ga…
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…
Carbon stars from LAMOST DR2 data
Wei Ji, Wenyuan Cui, Chao Liu +3
In this work, we present the new catalog of carbon stars from the LAMOST DR2 catalog. In total, 894 carbon stars are identified from multiple line indices measured from the stellar…
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…
A systematic search for the spectra with features of crystalline silicates in the Spitzer IRS Enhanced Products
Rui Chen, Ali Luo, Jiaming Liu +1
The crystalline silicates features are mainly reflected in infrared bands. The Spitzer Infrared Spectrograph (IRS) collected numerous spectra of various objects and provided a big…
An Efficient Method for Rare Spectra Retrieval in Astronomical Databases
Changde Du, Ali Luo, Haifeng Yang +2
One of important aims of astronomical data mining is to systematically search for specific rare objects in a massive spectral dataset, given a small fraction of identified samples…
