Tidally Trapped Two-pole Pulsations Discovered in a Close Binary with a Massive Cephei Star

Ping Li, Wen-Ping Liao, Sheng-Bang Qian +4

Tidally tilted pulsators (TTPs), whose pulsation axis aligns with the binary's semi-major axis, represent a newly established class of oscillators in binary systems. While all prev…

Superoutbursts and Positive Superhumps Occurred During the Standstill of a Z Cam-type Dwarf Nova

Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +4

Dwarf novae are semi-detached binaries, where a white dwarf accretes material from a cool main-sequence companion via an accretion disk, and are known for their intermittent outbur…
