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…
Activity indicators and stellar parameters of the Kepler targets. An application of the ROTFIT pipeline to LAMOST-Kepler stellar spectra
A. Frasca, J. Molenda-Zakowicz, P. De Cat +7
The LAMOST-Kepler survey, whose spectra are analyzed in the present paper, is the first large spectroscopic project aimed at characterizing these sources. Our work is focused at se…
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…
