Search for New Members of Young Asteroid Families

The search for new members of young asteroid families is of interest for studying the history of the formation of these families. The paper considers 17 young families. Young families are characterized by strong clustering of both proper and osculating orbital elements. When searching for candidates for new members of young families, the osculating orbital elements were analyzed. Kholshevnikov metrics were estimated, the behavior of nodes and pericenters was analyzed, and a search for low relative-velocity close encounters was performed. For all selected candidates, synthetic proper orbital elements were calculated using the OrbFit software package, based on which a conclusion was made about the belonging of the asteroid to the family. As a result, new members were found for eight young asteroid families.
