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…
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 post-common-envelope binary with double-peaked Balmer emission lines from TMTS
Qichun Liu, Xiaofeng Wang, Jie Lin +20
The dynamical method provides an efficient way to discover post-common-envelope binaries (PCEB) with faint white dwarfs (WDs), thanks to the development of time-domain survey proje…
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 photometric and spectroscopic study of eight semi-detached eclipsing binaries
Yajuan Lei, Guiping Zhou, Liang Wang +3
By cross-matching the eclipsing binary catalog from TESS with that from LAMOST MRS, semi-detached eclipsing binaries with radial velocities coverage spanning more than 0.3 phases w…
The disk reverberation mapping of the lensed quasar Q0957+561
Marcin Marculewicz, Mouyuan Sun, Zhixiang Zhang +1
The measurement of continuum time lags in lensed quasars can effectively probe the accretion physics of quasars. This is because microlensing observations of lensed quasars can pro…
