Properties of the optical component stars in X-ray binary systems
Jia Zhang, Sheng-Bang Qian, Guo-Bao Zhang +1
We collected a total of 4,058 X-ray binary stars, out of which 339 stars had three atmospheric parameters for optical companions from Gaia and LAMOST, while 264 stars had masses an…
A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
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…
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 Evolutionary States of EA-type Eclipsing Binaries Observed by LAMOST
S. -B. Qian, J. Zhang, J. -J. He +5
About 3196 EA-type binaries (EAs) were observed by LAMOST by June 16, 2017 and their spectral types were derived. Meanwhile stellar atmospheric parameters of 2020 EAs were determin…
The extraneous eclipses on binary light curves: KIC 5255552, KIC 10091110, and KIC 11495766
J. Zhang, S. B. Qian, S. M. Wang +3
Aims. We aim to find more eclipsing multiple systems and obtain their parameters, thus increasing our understanding of multiple systems. Methods. The extraneous eclipses on the \te…
Two twin binaries with nearly identical components: KIC 4826439 and KIC 6045264
Jia Zhang, Sheng-Bang Qian, Shu-Min Wang +2
Two twin binaries, KIC 4826439 and KIC 6045264, with very similar component stars were found photometrically based on eclipsing binary light curves. The absolute…
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,…
