cds-question@unistra.fryoung-stellar-objectsmilky-way-galaxyproper-motionsradial-velocitymorgan-keenan-classificationBased on published sources, we have created a kinematic database on 220 massive (>10M_{sun}_) young Galactic star systems located within <3 kpcof the Sun. Out of them, approximately 100 objects are spectroscopic binary and multiple star systems whose components are massive OB stars; the remaining objects are massive Hipparcos B stars with parallax errors of no more than 10 percent. Based on the entire sample, we have constructed the Galactic rotation curve, determined the circular rotation velocity of the solar neighborhood around the Galactic center R_0_=8kpc, V_0_=259+/-16km/s, and obtained the following spiral density wave parameters: the amplitudes of the radial and azimuthal velocity perturbations f_R_=-10.8+/-1.2km/s, and f_{theta}_=7.9+/-1.3km/s, respectively; the pitch angle for a two-armed spiral pattern i=-6.0+/-0.4deg, with the wavelength of the spiral density wave near the Sun being {lambda}=2.6+/-0.2kpc; and the radial phase of the Sun in the spiral density wave {chi}_{sun}_=-120+/-4{deg}. We show that such peculiarities of the Gould Belt as the local expansion of the system, the velocity ellipsoid vertex deviation, and the significant additional rotation can be explained in terms of the density wave theory. All these effects decrease noticeably once the influence of the spiral density wave on the velocities of nearby stars has been taken into account. The influence of Gould Belt stars on the Galactic parameter estimates has also been revealed. Eliminating them from the kinematic equations has led to the following new values of the spiral density wave parameters: f_{theta}_=2.9+/-2.1km/s and {chi}_{sun}_=-104+/-6{deg}.2013PAZh...39..601Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/39/601CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/39/601https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/39/601http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/39/601https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/39/601https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/39/601http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/39/601GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/39/601/stars (Basic data on stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/39/601/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/39/601/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/39/601/stars?GETtext/xml+votable180.050000true83.001658060.299081110.0055555555555555566/1198 1212 1299 1302 1339 1550 1554 1555 1633 2017 2806 2884 2970 3030 3053 3307 3384 3637 9478 12988 13557 14263 14305 14630 14631 14632 14644 14645 14646 14692 14807 14878 14919 15151 15250 15369 15478 15561 15573 15625 15683 15686 15713 15808 16144 17754 19676 19757 20517 20753 20782 20834 20900 20915 20923 21233 21401 21438 21439 21450 21456 21635 21641 21682 22039 22058 22249 22253 22258 22269 22615 22772 22854 22861 22862 22887 22889 22891 23007 23360 23637 23717 23749 23779 24186 24191 24370 24555 28809 28890 28891 28892 28944 29095 29118 29513 29838 30722 31169 31759 32174 32217 34041 36940 37012 37150 37212 37327 37333 37357 37662 37676 37682 37732 37816 37827 37854 37897 37923 37926 38016 38996 39075 39194 39201 39202 39209 39216 39217 39220 39227 39254 39297 39303 39355 39375 39397 39402 39671 39715 39739 39742 39832 39853 39863 39907 39916 40068 41606 41630 41655 41689 41747 41891 41916 41963 41982 41983 42071 42080 42113 42213 42356 42366 42383 42387 42394 42428 42449 42470 42618 42623 42652 42791 42800 42948 42977 42994 43011 43014 43024 43035 43048 43062 43099 43137 43211 43294 43338 43365 43383 43397 43407 43414 43416 43429 43460 43531 44306 44312 44316 44360 44366 44389 45964 47121 47648 47845https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/39/601?format=asciiOpticaldefaultJ/PAZh/39/601/starsBasic data on starse_HRVLine-of-sight velocity errorkm/sstat.errorfloatrecnoRecord number assigned by the VizieR team.
