A catalog of new slowly pulsating B-type stars
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +1
This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of TESS, LAMOST, and Gaia surveys, we have found 286…
Properties of the optical component stars in X-ray binary systems
Jia Zhang, Sheng-Bang Qian, Guo-Bao Zhang +1
We collected a total of 4,058 X-ray binary stars, out of which 339 stars had three atmospheric parameters for optical companions from Gaia and LAMOST, while 264 stars had masses an…
Comparative study of TESS photometry and radial velocities on six early K-type contact binaries with similar periods around 0.268 days
N. -P. Liu, S. -B. Qian, W. -P. Liao +2
High-precision light curves were extracted from TESScut images. Together with APOGEE and LAMOST medium resolution spectra, a joint study was made for six early K-type contact binar…
V606 Cen: A Newly Formed Massive Contact Binary in a Hierarchical Triple System
F. -X. Li, W. -P. Liao, S. -B. Qian +3
V606 Centauri (V606 Cen) is an early B-type close binary with an orbital period of 1.4950935\,d and the complete light curves are very difficult to be observed on the ground. By an…
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…
