Optical flares and flaring oscillations on the M-type eclipsing binary CU Cnc
Qian S. -B., J. Zhang, L. -Y. Zhu +7
We report here the discovery of an optical flare observed in R band from the red-dwarf eclipsing binary CU Cnc whose component stars are at the upper boundary of full convection (M…
A Circumbinary Planet in Orbit Around the Short-Period White-Dwarf Eclipsing Binary RR Cae
S. -B. Qian, L. Liu, L. -Y. Zhu +3
By using six new determined mid-eclipse times together with those collected from the literature, we found that the Observed-Calculated (O-C) curve of RR Cae shows a cyclic change w…
Circumbinary Planets Orbiting the Rapidly Pulsating Subdwarf B-type binary NY Vir
S. -B. Qian, L. -Y. Zhu, Z. -B. Dai +3
We report here the tentative discovery of a Jovian planet in orbit around the rapidly pulsating subdwarf B-type (sdB-type) eclipsing binary NY Vir. By using new determined eclipse…
CCD photometric study of the W UMa-type binary II CMa in the field of Berkeley 33
Liu Liang, Qian Shengbang, Zhu Liying +5
The CCD photometric data of the EW-type binary, II CMa, which is a contact star in the field of the middle-aged open cluster Berkeley 33, are presented. The complete R light curve…
Detection of a planetary system orbiting the eclipsing polar HU Aqr
S. -B. Qian, L. Liu, W. -P. Liao +7
Using the precise times of mid-egress of the eclipsing polar HU Aqr, we discovered that this polar is orbited by two or more giant planets. The two planets detected so far have mas…
The orbital period analyses for two cataclysmic variables: UZ Fornacis and V348 Puppis inside Period Gap
Z. -B. Dai, S. -B. Qian, E. Fernandez Lajus +1
Four newest CCD eclipse timings of the white dwarf for polar UZ Fornacis and Six updated CCD mid-eclipse times for SW Sex type nova-like V348 Puppis are obtained. The detailed O-C…
