Probing the Galactic Halo with RR Lyrae Stars -- V. Chemistry, Kinematics, and Dynamically Tagged Groups
Jonathan Cabrera Garcia, Timothy C. Beers, Yang Huang +9
We employ a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from the newly calibrated ------[Fe/H] and …
Probing the Galactic halo with RR Lyrae stars III. The chemical and kinematic properties of the stellar halo
Gaochao Liu, Yang Huang, Sarah Ann Bird +3
Based on a large spectroscopic sample of 4,300 RR Lyrae stars with metallicity, systemic radial velocity and distance measurements, we present a detailed analysis of the che…
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…
The Stellar "Snake" I: Whole Structure and Properties
Fan Wang, Hai-Jun Tian, Dan Qiu +10
To complement our previous discovery of the young snake-like structure in the solar neighborhood and reveal the structure's full extent, we build two samples of stars within the Sn…
Precise Ages of Field Stars From White Dwarf Companions in Gaia DR2
Dan Qiu, Hai-Jun Tian, Xi-Dong Wang +5
We analyze 4\,050 wide binary star systems involving a white dwarf (WD) and usually a main sequence (MS) star, drawn from the large sample assembled by \citet[][hereafter, T20]{Tia…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
Mapping the emission line strengths and kinematics of Supernova Remnant S147 with extensive LAMOST spectroscopic observations
Juan-Juan Ren, Xiao-Wei Liu, Bing-Qiu Chen +8
We present extensive spectroscopic observations of supernova remnant (SNR) S147 collected with the Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST). The spectra w…
The LAMOST spectroscopic survey of star clusters in M31. II. Metallicities, ages and masses
Chen Bingqiu, Liu Xiaowei, Xiang Maosheng +14
We select from Paper I a sample of 306 massive star clusters observed with the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and…
Quiescent luminous red galaxies (LRGs) as cosmic chronometers: on the significance of mass and environmental dependence
Gaochao Liu, Youjun Lu, Lizhi Xie +2
Massive luminous red galaxies (LRGs) are believed to be evolving passively and can be used as cosmic chronometers to estimate the Hubble constant. However, different LRGs may be lo…
On the Full Spectrum Fitting of Luminous Red Galaxies by Using ULySS and STARLIGHT
Gaochao Liu, Youjun Lu, Xuelei Chen +2
In this paper, we select a sample of quiescent luminous red galaxies (LRGs) from Sloan Digital Sky Survey Data Release 7 (SDSS DR7) with signal-to-noise ratio (S/N) substantially h…
Semi-Numerical Simulation of Reionization with Semi-Analytical Modeling of Galaxy Formation
Jie Zhou, Qi Guo, Gaochao Liu +3
In a semi-numerical model of reionization, the evolution of ionization fraction is simulated approximately by the ionizing photon to baryon ratio criterion. In this paper we incorp…
The Age-Redshift Relation For Luminous Red Galaxies Obtained From the Full Spectrum Fitting and Its Cosmological Implications
Gaochao Liu, Youjun Lu, Xuelei Chen +3
The relative age of galaxies at different redshifts can be used to infer the Hubble parameter and put constraints on cosmological models. We select 23,883 quiescent luminous red ga…
