Half a Million Binary Stars from the low resolution spectra of LAMOST
Yingjie Jing, Tian-Xiang Mao, Jie Wang +2
Binary stars are prevalent yet challenging to detect. We present a novel approach using convolutional neural networks (CNNs) to identify binary stars from low-resolution spectra ob…
Estimating the Atmospheric Parameters of Early-type Stars from the Chinese Space Station Telescope (CSST) Slitless Spectra Survey
JiaRui Rao, HaiLiang Chen, JianPing Xiong +6
The measurement of atmospheric parameters is fundamental for scientific research using stellar spectra. The Chinese Space Station Telescope (CSST), scheduled to be launched in 2024…
Detailed Mapping of the Galactic Disk Structure in the Solar Neighborhood through LAMOST K Dwarfs
Xi-Can Tang, Hao Tian, Jing Li +4
The Galactic disk is one of the main components of the Milky Way, which contributes most of the luminosity. Its structure is essential for understanding the formation and evolution…
All-sky Guide Star Catalog for CSST
Hui-Mei Feng, Zi-Huang Cao, Man I Lam +17
The China Space Station Telescope (CSST) is a two-meter space telescope with multiple back-end instruments. The Fine Guidance Sensor (FGS) is an essential subsystem of the CSST Pre…
The First Photometric Analysis of Two Low Mass Ratio Contact Binary Systems In TESS Survey
Qiyuan Cheng, Jianping XIong, Xu Ding +8
Low mass-ratio (q) contact binary systems are progenitors of stellar mergers such as blue straggles (BS) or fast-rotating FK Com stars. In this study, we present the first light cu…
A New Tidal Stream Discovered in Gaia DR3
Hao Tian, Chao Liu, Changqing Luo +2
Thanks to the precise astrometric measurements of proper motions by the Gaia mission, a new tidal stellar stream has been discovered in the northern hemisphere. The distribution of…
TYC 3340-2437-1: A Quadruple System with A Massive Star
Jiao Li, Chao Liu, Changqing Luo +10
Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution. The successive mergers of hi…
North-South asymmetries in the Galactic thin disk associated with the vertical phase spiral as seen using LAMOST-Gaia stars
Jun Lin, Rui Guo, Sarah A. Bird +5
We select 1,052,469 (754,635) thin disk stars from {\it Gaia} eDR3 and LAMOST DR7 in the range of Galactocentric radius (guiding center radius ) from 8 to 11\,kpc…
