A Helium-shell Burning Blue Horizontal Branch Star Produced from Common Envelope Evolution
Jiao Li, Changqing Luo, Hai-Liang Chen +16
Observationally, blue horizontal branch (BHB) stars are defined as hot stars occupying a characteristic region between the extreme blue horizontal branch and RR Lyrae variables in…
Stellar Parameters and Orbital Period Estimates for Composite-Spectrum sdB+MS Binaries from LAMOST
Jiangdan Li, Jianping Xiong, Jiao Li +5
Hot subdwarf (sdB) stars in binary systems with main-sequence (MS) companions provide valuable insights into mass transfer and envelope ejection processes in binary evolution. Thei…
Identify main-sequence binaries from the Chinese Space Station Telescope Survey with machine learning
Jia-jia Li, Jin-liang Wang, Kai-fan Ji +4
The statistical properties of double main sequence (MS) binaries are very important for binary evolution and binary population synthesis. To obtain these properties, we need to ide…
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…
