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…
First discovery of QPOs in the dwarf nova HS 2325+8205 based on TESS photometry
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +9
HS 2325+8205 is a long-period eclipsing dwarf nova with an orbital period above the period gap (Porb>3 h) and is reported to be a Z Cam-type dwarf nova. Based on the photometry of…
