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…
Decoding the Future of Exoplanets: Asteroseismic Confirmation of Subgiant and Red Giant Hosts
Wen-Xu Lin, Sheng-Bang Qian, Li-Ying Zhu +5
Asteroseismology has emerged as a powerful tool to unravel the intricate relationships between evolved stars and their planetary systems. In this study, we leverage this technique…
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…
Detection of two totally eclipsing B-type binaries with extremely low mass ratios
Linfeng Chang, Shengbang Qian, Lei Zang +1
The detection of O- and B-type stars with extremely low-mass companions is very important for understanding the formation and evolution of binary stars. However, their finding rema…
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…
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…
Using Asteroseismology to Calibrate the Physical Parameters of Confirmed Exoplanets and Their Evolved Host Stars
Wen-Xu Lin, Sheng-Bang Qian, Li-Ying Zhu +2
Asteroseismology offers a profound window into stellar interiors and has emerged as a pivotal technique in exoplanetary research. This study harnesses the Transiting Exoplanet Surv…
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…
