Characterizing Orbital Parameters of Hot Subdwarf Binaries with Multiple Spectroscopic Surveys
XInlin Zhao, Song Wang, Zhenxin Lei +5
Hot subdwarfs (HSDs) provide critical insights into the physical mechanisms governing binary evolution. In this work, we conduct a systematic analysis of 157 HSDs, selected from Ga…

The fractions of reflection effect systems detected in different subclasses of hot subdwarfs
Ruijie He, Xiangcun Meng, Zhenxin Lei
Hot subdwarfs with close low-mass M-type or brown dwarf companions usually show the reflection effect and often also eclipses. Through inspecting the light variations, we estimate…

Radial velocity variability fractions of different types of hot subdwarf stars
Ruijie He, Xiangcun Meng, Zhenxin Lei +2
Different types of hot subdwarfs may have different origins, which will cause them to present different radial velocity (RV) variability properties. Only 64% of our single-lin…
