LenghuSky-8: An 8-Year All-Sky Cloud Dataset with Star-Aware Masks and Alt-Az Calibration for Segmentation and Nowcasting
Yicheng Rui, Xiao-Wei Duan, Licai Deng +9
Ground-based time-domain observatories require minute-by-minute, site-scale awareness of cloud cover, yet existing all-sky datasets are short, daylight-biased, or lack astrometric…
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…
Cosmological model-independent test of CDM with two-point diagnostic by the observational Hubble parameter data
Shu-Lei Cao, Xiao-Wei Duan, Xiao-Lei Meng +1
Aiming at exploring the nature of dark energy (DE), we use forty-three observational Hubble parameter data (OHD) in the redshift range to make a cosmological…
Testing consistency of general relativity with kinematic and dynamical probes
Xiao-Wei Duan, Min Zhou, Tong-Jie Zhang
In this work, we test consistency relations between a kinematic probe, the observational Hubble data, and a dynamical probe, the growth rates for cosmic large scale structure, whic…
