CZ Aqr: an oscillating eclipsing Algol-type system composed of a Sct primary star and a subgiant star in a quadruple system
Qi-Huan Zeng, Wen-Ping Liao, Sheng-Bang Qian +3
Eclipsing Algol-type systems containing a Scuti (hereafter Sct) star enable precise determination of physical parameters and the investigation of stellar internal structu…

Evidence for a close-in tertiary orbiting around the Algol-type system HZ Dra with tidal splitting and spots activities
Ping Li, Wen-Ping Liao, Sheng-Bang Qian +7
We reported a cyclic variation of diagram with a semi-amplitude of 0.0033 days and a period of 1.05 years for the pulsating eclipsing binary HZ Dra. The cyclic variation can…

Exploring the physical properties of the Dor binary star RX Dra with photometry and asteroseismology
Li Ping, Liao Wen-Ping, Sun Qi-Bin +1
We model the TESS light curve of the binary system RX Dra, and also first calculate a lot of theoretical models to fit the g-mode frequencies previously detected from the TESS seri…
