Searching for Contact Binaries with LAMOST and TESS
Ting Wu, Jin-Zhong Liu, Senyu Qi +4
Contact binaries (CBs) serve as fundamental laboratories for studying complex stellar interactions, including mass transfer, tidal effects, and angular momentum loss. In this work,…
A Study of Cataclysmic Variables from the eFEDS Survey
Rui Wang, Wei-Min Gu, Zhi-Xiang Zhang +3
We present 17 cataclysmic variables (CVs) obtained from the crossmatch between the Sloan Digital Sky Survey (SDSS) and eROSITA Final Equatorial Depth Survey (eFEDS), including 8 kn…
A Be star-black hole binary with a wide orbit from LAMOST time-domain survey
Qian-Yu An, Yang Huang, Wei-Min Gu +21
Binary systems consisting of an early type star and a black hole (BH) are crucial for understanding various astrophysical phenomena, particularly the origins of detected gravitatio…
A Sample of Extreme Eclipsing Binaries with Accretion Disks from LAMOST and ZTF
Jiangxinxin Zhuang, Zhi-Xiang Zhang, Wei-Min Gu +1
Extreme eclipsing binaries may harbor peculiar physical properties. In this work, we aim to identify a sample of such systems by selecting binaries with pronounced eclipsing light…
Two Dynamically Discovered Compact Object Candidate Binary Systems from LAMOST Low-resolution Survey
Senyu Qi, Wei-Min Gu, Zhi-Xiang Zhang +3
We report two binary systems, LAMOST J035540+381550 (hereafter J035540) and LAMOST J035916+400732 (hereafter J035916), identified through the Large Sky Area Multi-Object Fiber Spec…
Searching for Compact Object Candidates from LAMOST Time-Domain Survey of Four K2 Plates
Senyu Qi, Wei-Min Gu, Tuan Yi +3
The time-domain (TD) surveys of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) yield high-cadence radial velocities, paving a new avenue to study binary sys…
The Nearest Neutron Star Candidate in a Binary Revealed by Optical Time-domain Surveys
Ling-Lin Zheng, Mouyuan Sun, Wei-Min Gu +19
The near-Earth (within pc) supernova explosions in the past several million years can cause the global deposition of radioactive elements (e.g., Fe) on Earth. The…
A White Dwarf-Main Sequence Binary Unveiled by Time-Domain Observations from LAMOST and TESS
Ling-Lin Zheng, Wei-Min Gu, Mouyuan Sun +16
We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
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…
Searching for compact objects in binaries with Gaia DR3
Jin-Bo Fu, Wei-Min Gu, Zhi-Xiang Zhang +4
We search for compact objects in binaries based on Gaia DR3. A sample of ten targets is derived under the conditions: radial velocity variable, low temperature ($T_{\rm eff} < 6000…
