A strange phenomenon of XZ Andromedae: two Keplerian periods with a 1:3 ratio
Jin-Zhao Yuan, Sheng-Bang Qian
Six mid-eclipse times of the eclipsing binary XZ And are obtained, which are analysed together with others collected from the literature. Two sets of cyclic variations with periods…
Z Draconis with two companions in a 2:1 mean-motion resonance
Jinzhao Yuan, Hakan Volkan Senavci, Shengbang Qian +1
All available mid-eclipse times of the eclipsing binary Z Draconis are analysed, and three sets of cyclic variations with periods of 20.1, 29.96 and 59.88 yr are found. The low-amp…
A Multicolour Photometric Study of the neglected eclipsing binary FT Ursae Majoris
Jin-Zhao Yuan
The multicolour photometric observations of the neglected eclipsing binary FT Ursae Majoris (FT UMa) were obtained in 2010. The 2003 version of Wilson-Devinney code was used to ana…
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…
First photometric study of the eclipsing binary PS Persei
Jinzhao Yuan
The CCD photometric observations of the eclipsing binary PS Persei (PS Per) were obtained on two consecutive days in 2009. The 2003 version Wilson-Devinney code was used to analyze…
