Detection of dark companions via the combination of eclipse timing variation, Hipparcos and/or Gaia astrometry: the cases of V Puppis and CY Ari
Guang-Yao Xiao, Fabo Feng, Song Wang +3
The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around…
Further evidence of shocks in the first-overtone RR Lyrae pulsators: first detection of shock-triggered magnesium emissions
Xiao-Wei Duan, Weijia Sun, Xiaodian Chen +2
The behavior of the shock wave in the atmosphere of the non-fundamental mode RR Lyrae pulsator remains a mystery. In this work, we firstly report a blueshifted Mg triplet emission…
Exploring the stellar rotation of early-type stars in the LAMOST Medium-Resolution Survey. II. Statistics
Weijia Sun, Xiao-Wei Duan, Licai Deng +1
Angular momentum is a key property regulating star formation and evolution. However, the physics driving the distribution of the stellar rotation rates of early-type main-sequence…
Possible evidence of hydrogen emission in the first-overtone and multi-mode RR Lyrae variables
Xiao-Wei Duan, Xiao-Dian Chen, Li-Cai Deng +4
The nature of shock waves in non-fundamental mode RR Lyrae stars remains a mystery because of limited spectroscopic observations. We apply a pattern recognition algorithm on spectr…
