KIC 6464285: A Solar-type Eclipsing Binary in a Hierarchical Triple System with Quasi-periodic Out-of-eclipse Modulations
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +10
We present the first detailed analysis of the solar-type triple system KIC 6464285. Combining long-term, high-precision photometry from Kepler, TESS, and ZTF with low-resolution sp…
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…
Long Photometric Cycles in Double Periodic Variables from Nodal Precession of a Tilted Accretion Disk
Cheng-Liang Jiao, Er-gang Zhao, Liying Zhu +1
We investigate whether the long photometric cycles observed in double-periodic variables (DPVs) can arise from nodal precession of a tilted accretion disk driven by the tidal torqu…
The new compact triple system: discovery of bright third star around contact binary using LAMOST-MRS spectra and photometry
Mikhail Kovalev, Azizbek Matekov, Sufen Guo +2
We present a study of the third star orbiting around known contact eclipsing binary J04+25 using spectra from the LAMOST medium-resolution survey (MRS) and publicly available photo…
KM UMa: An active short-period detached eclipsing binary in a hierarchical quadruple system
Fangbin Meng, Liying Zhu, Nianping Liu +4
The first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing b…
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…
TV Mon -- post mass transfer Algol type binary with Scuti pulsations in primary component
Mikhail Kovalev, Zhenwei Li, Jianping Xiong +4
We present a study of the detached eclipsing binary TV~Mon using spectra from the LAMOST medium-resolution survey and ASAS-SN, CoRoT photometry. We apply multiple-epochs spectral f…
Evidence for a close-in tertiary orbiting around the Algol-type system HZ Dra with tidal splitting and spots activities
Ping Li, Wen-Ping Liao, Sheng-Bang Qian +7
We reported a cyclic variation of diagram with a semi-amplitude of 0.0033 days and a period of 1.05 years for the pulsating eclipsing binary HZ Dra. The cyclic variation can…
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…
