VizieR Online Data Catalog: Gaia DR2 OB associations (Ward+, 2020)

We investigate the kinematic properties of a large number of independently selected OB associations. Using the OPTICS clustering algorithm, we select 109 likely OB associations from a large sample of OB stars within the Milky Way.

List of Gaia DR2 designations for all stars in the sample and corresponding association numbers in allstars.dat. Association positions and sizes in tablea1.dat. Association derived kinematic properties in tablea2.dat.
