An update of the catalog of radial velocity standard stars from the APOGEE DR17
Qing-Zheng Li, Yang Huang, Xiao-Bo Dong
We present an updated catalog of 46,753 radial velocity (RV) standard stars selected from the APOGEE DR17. These stars cover the Northern and Southern Hemispheres almost evenly, wi…
A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
Stellar Loci VI: An Updated Catalog of the Best and Brightest Metal-poor Stars
Shuai Xu, Haibo Yuan, Ruoyi Zhang +3
We employ Gaia, 2MASS, and ALLWISE photometry, as well as astrometric data from Gaia, to search for relatively bright very metal-poor ([Fe/H] ; VMP) giant star candidates u…
Photometric metallicity and distance estimates for 136,000 RR Lyrae stars from Gaia DR3
Xin-Yi Li, Yang Huang, Gao-Chao Liu +2
We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from our newly calibrated [Fe/H]/[Fe/H…
Li-rich Giants in LAMOST Survey. III. The statistical analysis of Li-rich giants
Yutao Zhou, Chun Wang, Hongliang Yan +5
The puzzle of Li-rich giant is still unsolved, contradicting the prediction of the standard stellar models. Although the exact evolutionary stages play a key role in the knowledge…
The value-added catalogue for LAMOST DR8 low-resolution spectra
Chun Wang, Yang Huang, Haibo Yuan +3
We present a value-added catalog containing stellar parameters estimated from 7.10 million low-resolution spectra for 5.16 million unique stars with spectral signal-to-noise ratios…
A spatially dependent correction of Gaia EDR3 parallax zero-point offset based on 0.3 million LAMOST DR8 giant stars
Chun Wang, Haibo Yuan, Yang Huang
We have studied the zero-point offset of Gaia early Data Release 3 (EDR3) parallaxes based on a sample of 0.3 million giant stars built from the LAMOST data with distance accuracy…
J-PLUS: Stellar Parameters, C, N, Mg, Ca and [α/Fe] Abundances for Two Million Stars from DR1
Lin Yang, Haibo Yuan, Maosheng Xiang +20
Context. The Javalambre Photometric Local Universe Survey (J-PLUS) has obtained precise photometry in twelve specially designed filters for large numbers of Galactic stars. Derivin…
At what mass are stars braked? The implication from the turnoff morphology of NGC 6819
Yong Yang, Chengyuan Li, Yang Huang +1
Extended main-sequence turnoffs apparent in most young and intermediate-age clusters (younger than ~2 Gyr) are known features caused by fast rotating early-type (earlier than F-typ…
Stellar Loci V: Photometric Metallicities of 27 Million FGK Stars based on Gaia Early Data Release 3
Shuai Xu, Haibo Yuan, Zexi Niu +3
We combine LAMOST DR7 spectroscopic data and Gaia EDR3 photometric data to construct high-quality giant (0.7 1.4) and dwarf (0.5 1.5) samples in the hi…
Stellar loci IV. Red giant stars
Ruoyi Zhang, Haibo Yuan, Xiaowei Liu +3
In the fourth paper of this series, we present the metallicity-dependent Sloan Digital Sky Survey (SDSS) stellar color loci of red giant stars, using a spectroscopic sample of red…
Metal-Poor Stars Observed with the Southern African Large Telescope II. An Extended Sample
Joseph Zepeda, Kaitlin C. Rasmussen, Timothy C. Beers +3
We present results from high-resolution (R ) spectroscopic observations of over 200 metal-poor stars, mostly selected from the RAVE survey, using the Southern African…
Beyond spectroscopy. I. Metallicities, distances, and age estimates for over twenty million stars from SMSS DR2 and Gaia EDR3
Yang Huang, Timothy C. Beers, Christian Wolf +8
Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galax…
Gaia EDR3 Parallax Zero-point Offset based on W Ursae Majoris-type Eclipsing Binaries
Fangzhou Ren, Xiaodian Chen, Huawei Zhang +3
We independently determine the zero-point offset of the Gaia early Data Release-3 (EDR3) parallaxes based on W Ursae Majoris (EW)-type eclipsing binary systems. EWs…
Correction to the photometric magnitudes of the Gaia Early Data Release 3
Lin Yang, Haibo Yuan, Ruoyi Zhang +4
In this letter, we have carried out an independent validation of the Gaia EDR3 photometry using about 10,000 Landolt standard stars from Clem & Landolt (2013). Using a machine lear…
A New Luminous blue variable in the outskirt of the Andromeda Galaxy
Yang Huang, Huaiwei Zhang, Chun Wang +8
The hot massive luminous blue variables (LBVs) represent an important evolutionary phase of massive stars. Here, we report the discovery of a new LBV -- LAMOST J0037+4016 in the di…
