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…
A potential mass-gap black hole in a wide binary with a circular orbit
Wang Song, Zhao Xinlin, Feng Fabo +28
Mass distribution of black holes identified through X-ray emission suggests a paucity of black holes in the mass range of 3 to 5 solar masses. Modified theories have been devised t…
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…
A Sample of Compact Object Candidates in Single-lined Spectroscopic Binaries from LAMOST Medium Resolution Survey
Hao-Bin Liu, Wei-Min Gu, Zhi-Xiang Zhang +3
The stellar spectra from LAMOST Medium Resolution Survey can be used to search for compact objects in binaries. The LAMOST DR10 catalog includes > 980, 000 targets with multiple me…
The hidden companion in J1527: a 0.69 solar-mass white dwarf?
Zhi-Xiang Zhang, Hao-Bin Liu, Tuan Yi +2
Finding nearby neutron stars can probe the supernova and metal-enrichment histories near our Solar system. Recently, Lin et al. 2023 reported an exciting neutron star candidate, 2M…
The Binary Broadening Function
Tuan Yi
We propose an extended formalism for the spectral broadening function (BF) based on the multiplication rule of block matrices. The formalism, which we named the binary broadening f…
