The W-subtype active contact binary PZ UMa with a possible more massive tertiary component
X. Zhou, B. Soonthornthum
Two sets of multiple-color () light curves of PZ UMa were observed in dependently with the 2.4 meter telescope at the Thai National Observatory and the 1 meter tele…
V752 Cen -- A triple-lined spectroscopic contact binary with sudden and continuous period changes
X. Zhou, B. Soonthornthum, S. -B. Qian +2
V752 Cen is a triple-lined spectroscopic contact binary. Its multi-color light curves were obtained in the years 1971 and 2018, independently. Photometric analyses reveal that the…
Photometric investigation on the W-subtype contact binary V1197 Her
Xiao Zhou, Boonrucksar Soonthornthum
Multi-color light curves of V1197 Her were obtained with the 2.4 meter optical telescope at Thai National Observatory and the Wilson-Devinney (W-D) program is used to model the obs…
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…
