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…
Evolutionary states and triplicity of four massive semi-detached binaries with long-term decreasing orbital periods in the LMC
Fu-Xing Li, Sheng-Bang Qian, Li-ying Zhu +6
The massive semi-detached binary with a long-term decreasing orbital period may involve a rapid mass-transfer phase in Case A, and thus they are good astrophysical laboratories for…
A New IW And-Type Star: Karachurin 12 with Tilted Disks and Diverse cycles
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +4
The IW And-type phenomenon in cataclysmic variables presents a significant challenge to the accretion disk instability model. Using photometric data from the All-Sky Automated Surv…
Tilted Disk Precession and Negative Superhumps in HS 2325+8205: A Multi-Window Analysis
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +3
Tilted disk precession exists in different objects. Negative superhumps (NSHs) in cataclysmic variable stars (CVs) are believed to arise from the interaction between the reverse pr…
Five New Heartbeat Star Systems with Tidally Excited Oscillations Discovered Based on TESS Data
Min-Yu Li, Sheng-Bang Qian, Ai-Ying Zhou +6
Heartbeat stars (HBSs) with tidally excited oscillations (TEOs) are ideal astrophysical laboratories for studying the internal properties of the systems. In this paper, five new HB…
Twenty-three New Heartbeat Star Systems Discovered Based on TESS Data
Min-Yu Li, Sheng-Bang Qian, Ai-Ying Zhou +6
Heartbeat stars (HBSs) are ideal astrophysical laboratories to study the formation and evolution of binary stars in eccentric orbits and the internal structural changes of their co…
Comparison of the Origin of Short Gamma-Ray Bursts with or without Extended Emission
Qin-Mei Li, Qi-Bin Sun
The merger of compact binary stars produces short gamma-ray bursts (sGRBs), involving channels such as neutron star - neutron star (BNS) and neutron star - black hole (NS-BH). The…
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…
KIC 7914906: An Eclipsing Heartbeat Star with Tidally Excited Oscillations and Gamma Doradus/Delta Scuti Hybrid Pulsations
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +6
We present the eclipsing Heartbeat Star KIC 9704906 with tidally excited oscillations (TEOs) and gamma Doradus/delta Scuti hybrid pulsations. The derived parameters show that it ha…
Pulsation Phases and Mode Identification of Tidally Excited Oscillations in Fourteen Kepler Heartbeat Stars
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +6
Tidally excited oscillations (TEOs) in Heartbeat Stars (HBSs) are an essential probe of the internal properties of the systems, but their potential has yet to be fully exploited. B…
A New Window for Studying Intermediate Polars and Tilted Accretion Disk Precession
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +5
TV Col is a long-period eclipsing intermediate polar (IPs) prototype star for the negative superhump (NSH) system. We investigate the eclipse minima, eclipse depth, and NSH amplitu…
