CW Cas: A solar-type contact binary system with an unseen third companion in a hierarchical quadruple system
Azizbek Matekov, Liying Zhu, Linjia Li +11
We present a comprehensive multiband photometric and spectroscopic study of the G-type binary CW Cas whose parameters have not been well determined. Our double-lined spectroscopic…
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…
Deep and low mass-ratio contact binaries and their third bodies
Liying Zhu, Shengbang Qian, Wenping Liao +6
Deep and low mass-ratio contact binaries (DLMCBs) are believed to be in the final stage of their contact phase, potentially leading to the formation of fast-rotating single stars s…
CSS_J154915.7+375506: A low-mass-ratio marginal contact binary system with a hierarchical third body
Jin-Feng Wu, Li-Ying Zhu, Azizbek Matekov +6
We presented the multi-filter light curves of CSS_J154915.7+375506 inaugurally, which were observed by the 1.5 m AZT-22 telescope at Maidanak Astronomical Observatory. A low-resolu…
