Searching for Hyper-compact star clusters in the Milky Way using LAMOST and Gaia
Hao Wu, Haibo Yuan, Yilun Wang +2
During the early merger of the Milky Way, intermediate-mass black holes in merged dwarf galaxies may have been ejected from the center of their host galaxies due to gravitational w…
Astrometric mass measurement of compact companions in binary systems with Gaia
Yilun Wang, Shilong Liao, Nicola Giacobbo +3
For binary systems with an unseen primary and a luminous secondary, the astrometric wobble of the secondary could be used to study the primary. With Gaia, it is possible to measure…
Searching for new globular clusters in M 31 with Gaia EDR3
Yilun Wang, Haibo Yuan, Bingqiu Chen +4
We found 50 new globular cluster (GC) candidates around M\,31 with Gaia Early Data Release 3 (EDR3), with the help from Pan-STARRS1 DR1 magnitudes and Pan-Andromeda Archaeological…
Not that simple: the metallicity dependence of the wide binary fraction changes with separation and stellar mass
Zexi Niu, Haibo Yuan, Yilun Wang +1
The metallicity dependence of the wide binary fraction (WBF) is critical for studying the formation of wide binaries. While controversial results have been found in recent years. H…
LAMOST Time-Domain Survey: First Results of four 2 plates
Song Wang, Haotong Zhang, Zhongrui Bai +23
From Oct. 2019 to Apr. 2020, LAMOST performs a time-domain spectroscopic survey of four 2 plates with both low- and med-resolution observations. The low-resolution spectroscopic…
Machine Learning Regression of extinction in the second Data Release
Yu Bai, JiFeng Liu, YiLun Wang +1
Machine learning has become a popular tool to help us make better decisions and predictions, based on experiences, observations and analysing patterns within a given data set witho…
A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
