First photometric study of ultrashort-period contact binary 1SWASP J140533.33+114639.1
Bin Zhang, Sheng-bang Qian, R. Michel +2
In this paper, CCD photometric light curves for the short-period eclipsing binary 1SWASP J140533.33+114639.1 (hereafter J1405) in the bands are presented and analyzed using t…
Physical Properties and Evolutionary States of EA-type Eclipsing Binaries Observed by LAMOST
S. -B. Qian, J. Zhang, J. -J. He +5
About 3196 EA-type binaries (EAs) were observed by LAMOST by June 16, 2017 and their spectral types were derived. Meanwhile stellar atmospheric parameters of 2020 EAs were determin…

Double cyclic variations in orbital period of the eclipsing cataclysmic variable EX Dra
Zhong-tao Han, Sheng-bang Qian, Irina Voloshina +1
EX Dra is a long-period eclipsing dwarf nova with mag amplitude outbursts. This star has been monitored photometrically from November, 2009 to March, 2016 and 29 new mid-…
Long-term photometric behavior of the eclipsing cataclysmic variable V729 Sgr
Han Zhongtao, Qian Shengbang, Lajús +3
We present the analysis results of an eclipsing cataclysmic variable (CV) V729 Sgr, based on our observations and AAVSO data. Some outburst parameters were determined such as outbu…
Long-term photometric behaviour of the eclipsing Z Cam-type dwarf nova AY Psc
Zhong-tao Han, Sheng-bang Qian, Irina Voloshina +1
New eclipse timings of the Z Cam-type dwarf nova AY Psc were measured and the orbital ephemeris was revised. Based on the long-term AAVSO data, moreover, the outburst behaviors wer…
