Tracing the Origin of Moving Groups. III. Detecting Moving Groups in The LAMOST DR7

Yong Yang, Jingkun Zhao, Jiajun Zhang +2

We revisit the moving groups (MGs) in the solar neighborhood with a sample of 91969 nearby stars constructed from LAMOST DR7. Using the wavelet technique and Monte Carlo simulation…
