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 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…
Physical parameters and orbital period variation of a newly discovered cataclysmic variable GSC 4560-02157
Zhong-tao Han, Sheng-bang Qian, Irina Voloshina +3
GSC 4560-02157 is a new eclipsing cataclysmic variable with an orbital period of days. By using the published and band data together with our observations, we d…
WZ Sge: an eclipsing cataclysmic variable evolving towards the period minimum
Z. -T. Han, S. -B. Qian, Irina Voloshina +1
We present the photometric results of the eclipsing cataclysmic variable (CV) WZ Sge near the period minimum (). Eight new mid-eclipse times were determined and the orbita…
