Diversity in Evolutionary Status and Magnetic Activity among Solar-Type Twin Detached Eclipsing Binaries
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +9
We present a combined photometric and spectroscopic analysis of four detached eclipsing binaries (KIC 8957954, KIC 10593759, KIC 8302455, and TIC 207398432), all of which exhibit c…
IY Lyr: A Thick-Disk first-overtone RR Lyrae Star with a Possible Neutron Star Companion
Linjia Li, Shengbang Qian, Ildar Asfandiyarov +10
IY Lyr, historically misclassified as an eclipsing binary, has been previously identified as a first-overtone RR Lyrae star (RRc star). Using multiband photometry (All-Sky Automate…
Photometric and Spectroscopic Analysis of V583 Lyrae, an Algol with a g-mode Pulsating Primary and Accretion Disk
Hui-Ting Zhang, Sheng-Bang Qian, Wen-Ping Liao +2
V583 Lyr is an extremely low mass ratio Algol-type binary with an orbital period of 11.2580 days. We determined an effective temperature of T_{eff1} = 9000 \pm 350 K from newly obs…
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In this study, all unpublished time series photometric data of BM UMa ( 2.0, P = 0.2712\,d) from available archives were re-investigated together with new data taken from t…
Spectroscopic properties of the dwarf nova-type cataclysmic variables observed by LAMOST
Han Zhongtao, Boonrucksar Soonthornthum, Qian Shengbang +5
Spectra of 76 known dwarf novae from the LAMOST survey were presented. Most of the objects were observed in quiescence, and about 16 systems have typical outburst spectra. 36 of th…
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…
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…
