Chemical abundances of 20 barium stars from the OHP spectra
Guochao Yang, Jingkun Zhao, Yanchun Liang +7
Based on the high resolution and high signal-to-noise spectra, we derived the chemical abundances of 20 elements for 20 barium (Ba-) stars. For the first time, the detailed abundan…
An X-Ray-dim "Isolated'' Neutron Star in a Binary?
Jie Lin, Chunqian Li, Weiyang Wang +13
We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modelling of th…
Stellar Atmospheric Parameters of M-type Stars from LAMOST DR8
Ming-Yi Ding, Jian-Rong Shi, Yue Wu +9
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data of M-type stars, and the derive…
Lithium Evolution of Giant Stars Observed by LAMOST and Kepler
Jinghua Zhang, Jian-Rong Shi, Hong-Liang Yan +8
Mapping lithium evolution for evolved stars will provide restrictions and constraints on the fundamental stellar interior physical processes, which further shed light on our unders…
Chemical abundances of three new Ba stars from the Keck/HIRES spectra
Shuai Liu, Liang Wang, Jian-Rong Shi +4
Based on high resolution, high signal-to-noise (S/N) ratio spectra from Keck/HIRES, we have determined abundances of 20 elements for 18 Ba candidates. The parameter space of these…
Chemical and Kinematic Properties of the Galactic Disk from the LAMOST and Gaia Sample Stars
Yepeng Yan, Cuihua Du, Shuai Liu +5
We determined the chemical and kinematic properties of the Galactic thin and thick disk using a sample of 307,246 A/F/G/K-type giant stars from the LAMOST spectroscopic survey and…
The substructures in the local stellar halo from Gaia and LAMOST
Hefan Li, Cuihua Du, Shuai Liu +2
Based on the second Gaia data release (Gaia DR2) and spectroscopy from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data, we identified 20,089 halo stars…
The high velocity stars in the Local Stellar Halo from Gaia and LAMOST
Cuihua Du, Hefan Li, Shuai Liu +2
Based on the first Gaia data release and spectroscopy from the LAMOST Data Release 4, we study the kinematics and chemistry of the local halo stars. The halo stars are identified k…
Metallicity and Kinematics of the Galactic halo from the LAMOST sample stars
Shuai Liu, Cuihua Du, Heidi Jo Newberg +8
We study the metallicity distribution and kinematic properties of 4,680 A/F/G/K-type giant stars with 5 kpc selected from the LAMOST spectroscopic survey. The metallicity di…
