A General Framework for Radial Velocity Calibration in Low-Resolution Spectroscopic Surveys: Correcting Wavelength-Dependent and Global Systematics with Application to LAMOST DR9

Jinming Zhang, Haibo Yuan, Zhijia Tian

Radial velocity (RV) is crucial for stellar kinematics and Galactic archaeology. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has obtained over ten millio…

Identify Main-sequence Binaries from the Chinese Space Station Telescope Survey with Machine Learning. II. Based on Gaia and GALEX

Jia-jia Li, Jian-ping Xiong, Zhi-jia Tian +3

The statistical characteristics of double main-sequence (MS) binaries are essential for investigating star formation, binary evolution, and population synthesis. Our previous study…

Period-Luminosity-Metallicity-Color Relations of Late-type Contact Binaries in the Big Data Era

Lian-Yun Song, Zhi-Jia Tian

Binary stars ubiquitous throughout the universe are important. Contact binaries (CBs) possessing Period-Luminosity (PL) relations could be adopted as distance tracers. The PL relat…

The rotation curve and mass distribution of M31

Xiangwei Zhang, Bingqiu Chen, Pinjian Chen +2

To gain a better understanding of the Andromeda galaxy M31 and its role in the Local Group, measuring its mass precisely is essential. In this work, we have constructed the rotatio…

Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: VIII: Mapping the kinematics of the Galactic disk using mono-age and mono-abundance stellar populations

Weixiang Sun, Yang Huang, Han Shen +5

We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a larg…

Probing the galactic halo with RR Lyrae stars I: The catalog

G. -C. Liu, Y. Huang, H. -W. Zhang +10

We present a catalog of 5,290 RR Lyrae stars (RRLs) with metallicities estimated from spectra of the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) and the Sl…
