A Machine Learning Approach to Search for Open Star Clusters in the Milky Way
A catalogue of 74 new open clusters found in Gaia Data-Release 2
We employ an unsupervised machine learning method to blindly search for open star clusters in the galactic latitude range of |b| < 20 degrees.In addition to 2,080 known clusters, 74 new open cluster candidates are found.The positions, apparent radii, parallaxes, proper motions and memberstars of these candidates are presented.To obtain the physical parameters of each candidate cluster, stellar isochrones are fitto the photometric data.The results show that the apparent radii and the observed proper motion dispersions of these new candidates are consistent with those of open clusters previously identified in gaia dr2.
