cds-question@unistra.frstellar-associationsradial-velocityThe main objective of this study is the characterization of the velocity field in the Cygnus OB1 association using the radial velocity data currently available in the literature. This association is part of a larger star-forming complex located in the direction of the Cygnus region, but whose main subsystems may be distributed at different distances from the sun. We have collected radial velocity data for more than 300 stars in the area of 5x5 square degrees centred on the Cygnus OB1 association. We present the results of a kinematic clustering analysis in the subspace of the phase space formed by angular coordinates and radial velocity using two independent methodologies. We have found evidence of structure in the phase space with the detection of two main groups, corresponding to different radial velocity and distance values, belonging to the association, and associated with two main shells defined by the Halpha emission. A third grouping well separated from the other two in velocity appears to occupy the whole region associated with what has been called "common shell".2017MNRAS.465.3879Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/465/3879CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/465/3879https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/465/3879http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/465/3879https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/465/3879https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/465/3879http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/465/3879GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/465/3879/table1 (Radial velocity data for 314 stars in the Cygnus OB1 association)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/465/3879/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/465/3879/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/465/3879/table1?GETtext/xml+votable180.050000true301.27538.48330.0055555555555555565/3655 3657 3660-3662 6/14607 14614-14615 14617-14619 14636-14637 14652-14654 14666 14688-14690 14737https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/465/3879?format=asciiOpticaldefaultJ/MNRAS/465/3879/table1Radial velocity data for 314 stars in the Cygnus OB1 associationHD?
