Abstract:

We present the use of the scikit-learn DBSCAN clustering code as a machine learning tool to test the membership and integrity of apparent open clusters to distinguish asterisms from real open clusters in the Gaia DR3 3D data space. For testing means, we studied known Open Clusters NGC 1798 and NGC 6633. In the field of NGC 1798 we accidentally confirmed an Open Cluster LP17. For final analyze, we processed the 11 open clusters of Dolidze-Jimsheleishvili as the most of them are small having low spatial density and are hard to confirm as an Open Clusters with other methods. As a result, we report that 3 of them show clustering tendency as the open clusters: DolidzeDzim 6, DolidzeDzim 7 and DolidzeDzim 10.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
