Evolution of negative superhumps, quasi-periodic oscillations and outbursts in the Z Cam-type dwarf nova AH Her
Qi-Bin Sun, Sheng-Bang Qian, Min-Yu Li
AH Her is a Z Cam-type dwarf nova with an orbital period of ~ 0.258 d. Dwarf nova oscillations and long-period dwarf nova oscillations have been detected, but no quasi-periodic osc…
Nine New Cataclysmic Variable Stars with Negative Superhumps
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +5
Negative superhumps (NSHs) are signals a few percent shorter than the orbital period of a binary star and are considered to originate from the reverse precession of the tilted disk…
Detection of Tidally Excited Oscillations in Kepler Heartbeat Stars
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +6
Heartbeat stars (HBSs) with tidally excited oscillations (TEOs) are ideal laboratories for studying the effect of equilibrium and dynamical tides. However, studies of TEOs in Keple…
New evidence for the precession of tilted disk in SDSS J081256.85+191157.8
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +5
Super-orbital signals and negative superhumps are thought to be related to the reverse precession of the nodal line in a tilted disk, but the evidence is lacking. Our results provi…
