NLTE Analysis of High Resolution H-band Spectra. II. Neutral Magnesium
Junbo Zhang, Jianrong Shi, Kaike Pan +2
Aiming at testing the validity of our magnesium atomic model and investigating the effects of non-local thermodynamical equilibrium (NLTE) on the formation of the H-band neutral ma…
NLTE Analysis of High Resolution H-band Spectra. I. Neutral Silicon
Junbo Zhang, Jianrong Shi, Kaike Pan +2
We investigated the reliability of our silicon atomic model and the influence of non-local thermodynamical equilibrium (NLTE) on the formation of neutral silicon (Si I) lines in th…
Masses and Ages for 230,000 LAMOST Giants, via Their Carbon and Nitrogen Abundances
Anna Y. Q. Ho, Hans-Walter Rix, Melissa K. Ness +3
We measure carbon and nitrogen abundances to 0.1 dex for 450,000 giant stars from their low-resolution (R1800) LAMOST DR2 survey spectra. We use these [C/M] and [N…
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…
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…
Characterizing the SHARDS of Disrupted Milky Way Satellites with LAMOST
Jeffrey L. Carlin, Chao Liu, Heidi Jo Newberg +7
We derive the fraction of substructure in the Galactic halo using a sample of over 10,000 spectroscopically-confirmed halo giant stars from the LAMOST spectroscopic survey. By obse…
