Long-term high-resolution spectroscopic monitoring of the evolved metal-poor binary PS Gem
V. G. Klochkova, V. E. Panchuk, J. K. Zhao +3
We present results of long-term high-resolution spectroscopic monitoring of the extremely low-metallicity star PS Gem (=HD 52961), associated with IRAS 07008+1050. The spectra were…
The Stellar Abundances and Galactic Evolution Survey (SAGES). V. The First Data Release of the DDO51 Band
Qiqian Zhang, Zhou Fan, Gang Zhao +20
We present the first public data release of DDO51 band from the Stellar Abundances and Galactic Evolution Survey (SAGES), based on Nanshan One-meter Wide-field Telescope (NOWT) obs…
The Stellar Abundances and Galactic Evolution Survey (SAGES). IV. Surface Gravity Estimation and Giant-Dwarf Separation with the DDO51 Filter
Qiqian Zhang, Zhou Fan, Gang Zhao +16
Reliable estimation of stellar surface gravity (log ) for a large sample is crucial for evaluating stellar evolution models and understanding galactic structure; However, it is…
High-α-Metal-Rich stars in the LAMOST-MRS survey and its connection with the galactic bulge
Haopeng Zhang, Yuqin Chen, Gang Zhao +6
We report the detection of a large sample of high--metal-rich stars on the low giant branch with dex in the LAMOST-MRS survey. This special group corresponds to a…
Exploring the Galactic Anticenter substructure with LAMOST & Gaia DR2
Jing Li, Xiang-Xiang Xue, Chao Liu +12
We characterize the kinematic and chemical properties of 589 Galactic Anticenter Substructure Stars (GASS) with K-/M- giants in Integrals-of-Motion space. These stars likely includ…
Tracing Kinematic and Chemical Properties of Sagittarius Stream by K-Giants, M-Giants, and BHB stars
Chengqun Yang, Xiang-Xiang Xue, Jing Li +12
We characterize the kinematic and chemical properties of 3,000 Sagittarius (Sgr) stream stars, including K-giants, M-giants, and BHBs, select from SEGUE-2, LAMOST, and SDSS s…
