BM UMa: a middle shallow contact binary at pre-transition stage of evolution from W-type to A-type
T. Sarotsakulchai, B. Soonthornthum, S. Poshyachinda +3
In this study, all unpublished time series photometric data of BM UMa ( 2.0, P = 0.2712\,d) from available archives were re-investigated together with new data taken from t…
Comprehensive Photometric Investigation of an Active Early K-type Contact System -- IL Cnc
N. -P. Liu, T. Sarotsakuchai, S. Rattanasoon +1
Comprehensive photometric investigation was carried out to the early K-type contact binary - IL Cnc. A few light curves from both ground-based telescopes and the Kepler space teles…
YZ Phe: an active contact binary with variation of the O'Connell effect and orbital period change
T. Sarotsakulchai, S. -B. Qian, B. Soonthornthum +7
YZ Phe is a very short-period contact binary (Sp.= ) with an orbital period of 0.2347 days near the short period limit (0.22 d). We present the complete light curves in $VRI…
Photometric Investigation of the Contact Binary GU Ori with High Metallicity
Xiao Zhou, Shengbang Qian, Boonrucksar Soonthornthum +5
GU Ori was observed with the 1m telescope at Yunnan Observatories in 2005. To determine its physical properties, the Wilson-Devinney program is used. The results reveal that GU Ori…
DE CVn: an eclipsing post-common envelope binary with a circumbinary disk and a giant planet
Z. T Han, S. B. Qian, L. Y. Zhu +8
We present a timing analysis of the eclipsing post-common envelope binary (PCEB) DE CVn. Based on new CCD photometric observations and the published data, we found that the orbital…
New Photometric Investigation of the Low-Mass-Ratio Contact Binary Star V1853 Orionis
Jia-Jia He, Sheng-Bang Qian, B. Soonthornthum +3
Four-color charge-coupled device (CCD) light curves in , , and bands of the total-eclipsing binary system, V1853 Ori, are presented. By comparing our light curves w…
TY Pup: a low-mass-ratio and deep contact binary as a progenitor candidate of luminous red novae
T. Sarotsakulchai, S. B. Qian, B. Soonthornthum +6
TY Pup is a well-known bright eclipsing binary in southern hemisphere with an orbital period of 0.8192 days. New light curves in bands were obtained with the 0.61-m…
RW Dor: A G-type shallow contact binary with new orbital period investigation
T. Sarotsakulchai, S. -B. Qian, B. Soonthornthum +9
New CCD photometric light curves of short period (P=0.285d) eclipsing binary RW Dor are presented. The observations performed with the PROMPT-8 robotic telescope at CTIO in Chile f…
