An extremely low mass ratio contact binary NW Aps with a potential compact companion star
Xiao Zhou
The photometric solutions of NW Aps reveal that it is a low mass ratio () contact binary system. Investigation of orbital period shows that its orbital period is increas…
Multi-color and TESS photometric investigation of four lo mass-ratio contact binary systems
Ahmed Waqas Zubairi, Zhao Ergang, Qian Shengbang +2
We present the TESS and BVRcIc light curves solution of four low mass-ratio contact binary systems TIC 159102550), V1068 Her, MW Pav and TIC 321576458. Except MW Pav, all three sys…
Orbital period correction and light curve modeling of the W-subtype shallow contact binary OWLeo
Xiao Zhou, Shengbang Qian
Orbital period and multi-color light curves' investigation of OW Leo are presented for the first time. The orbital period of OW Leo is corrected from days to $P = 0.…
ASAS J174406+2446.8 is identified as a marginal-contact binary with a possible cool third body
Xiang-Dong Shi, Sheng-Bang Qian, Lin-Jia +2
ASAS J174406+2446.8 was originally found as a Scuti-type pulsating star with the period P=0.189068 by ASAS survey. However, the LAMOST stellar parameters reveal that it…
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…
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…
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…
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…
Physical Properties and Catalogue of EW-type Eclipsing Binaries Observed by LAMOST
S. -B. Qian, J. -J. He, J. Zhang +4
Numerous EWs were discovered by several deep photometric survey and there are about 40785 EW-type binary systems listed in the international variable star index (VSX) by March 13,…
Physical properties and evolutionary status of the W-subtype contact binary V502 Oph with a stellar companion
Xiao Zhou, Shengbang Qian, Binghe Huang +2
Multi-color ( ) CCD photometric light curves of the contact binary V502 Oph are analyzed using the Wilson-Devinney (W-D) program. The solutions reveal that V502 O…
A low-mass-ratio and deep contact binary as the progenitor of the merger V1309 Sco
Li-Ying Zhu, Er-Gang Zhao, Xiao Zhou
Nova Sco 2008 (=V1309 Sco) is an example of a V838 Mon type eruption rather than a typical classical nova. This enigmatic object was recently shown to have resulted from the merger…
