Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
The authors re‑examine the object G6096, previously thought to be a wide binary with a compact companion, and using spectroscopy, radial‑velocity and astrometric analysis together…
Hunting for Compact Object Binaries from eRASS1 Optical Counterparts through ZTF Time-domain Photometry and Multi-wavelength Census
Xin-Yu Fang, Hao-Bin Liu, Wei-Min Gu
Capitalizing on the eRASS1 optical counterpart catalog, we conduct a systematic census of compact object binary (COB) candidates, with a primary focus on X-ray binaries (XRBs), by…
Probing Compact Objects in Wide-Orbit Binaries with Joint LAMOST LRS and MRS
Hao-Bin Liu, Wei-Min Gu
Wide-orbit binaries serve as crucial laboratories for understanding stellar evolution and identifying quiescent compact objects. In this work, we search for compact objects in wide…
Weighing Hidden Companions of Compact Object Candidates via Rotational Broadening
Rui Wang, Zhi-Xiang Zhang, Wei-Min Gu +3
The determination of unseen companion masses () is essential for identifying compact objects in binary systems, yet obtaining reliable orbital inclinations remains one of the…
Searching for Accreting Compact Object Binaries in SRG/eROSITA eRASS1
Hao-Bin Liu, Wei-Min Gu, Yongqi Lu +2
Compact object binaries with accreting white dwarfs, neutron stars, or black holes are crucial for understanding accretion physics. In this study, we identify accreting compact obj…
