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…
The Red Supergiant Progenitor of the Type II Supernova 2024abfl
Jingxiao Luo, Lifu Zhang, Bing-Qiu Chen +9
Linkage between core-collapse supernovae (SNe) and their progenitors is not fully understood and ongoing effort of searching and identifying the progenitors is needed. $\mathrm{SN\…
Fundamental Parameters of a Binary System Consisting of a Red Dwarf and a Compact Star
Xu Ding, KaiFan Ji, ZhiMing Song +7
TIC 157365951 has been classified as a Scuti type by the International Variable Star Index (VSX). Through the spectra from Large Sky Area Multi-Object Fiber Spectroscopic Tele…
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…
A Method of Rapidly Deriving Late-type Contact Binary Parameters and Its Application in the Catalina Sky Survey
JinLiang Wang, Xu Ding, JiaJia Li +3
With the continuous development of large optical surveys, a large number of light curves of late-type contact binary systems (CBs) have been released. Deriving parameters for CBs u…
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…
