cds-question@unistra.fropen-star-clustersstellar-associationsradial-velocityWe have redetermined kinematic parameters of the Gould Belt using currently available data on the motion of nearby young (logt<7.91) open clusters, OB associations, and moving stellar groups. Our modeling shows that the residual velocities reach their maximum values of -4km/s for rotation (in the direction of Galactic rotation) and +4km/s for expansion at a distance from the kinematic center of 300pc. We have taken the following parameters of the Gould Belt center: R_0_=150pc and l_0_=128{deg}. The whole structure is shown to move relative to the local standard of rest at a velocity of 10.7+/-0.7km/s in the direction l=274+/-4{deg} and b=-1+/-3{deg}. Using the derived rotation velocity, we have estimated the virial mass of the Gould Belt to be 1.5 million solar masses.2006PAZh...32..906Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/32/906CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/280 : All-sky Compiled Catalogue of 2.5 million stars (ASCC-2.5)J/A+A/438/1163 : Catalogue of Open Cluster Data (COCD-1) (Kharchenko+, 2005)J/A+A/440/403 : 109 new Galactic open clusters (COCD-2) (Kharchenko+, 2005)J/AZh/83/821 : Compiled stellar radial velocities catalog (OSACA)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/32/906https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/32/906http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/32/906https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/32/906https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/32/906http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/32/906GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/32/906/data (Space velocities of open clusters and OB associations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/32/906/data?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/32/906/data?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/32/906/data?GETtext/xml+votable180.050000true6/1545 14081 14603 14878 15651 15693 20761 21438 21439 22056 22805 22854 22862 22880 22892 22893 22895 22993 23569 23717 24094 31790 34054 34850 36956 37012 37231 37332 37592 37659 37790 37863 38382 39181 39216 39251 39354 39697 39714 39739 42650 43148 44353https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/32/906?format=asciiOpticaldefaultJ/PAZh/32/906/dataSpace velocities of open clusters and OB associationso_RVNumber of stars used for calculation of RVmeta.numberintrecnoRecord number assigned by the VizieR team.
