cds-question@unistra.fropen-star-clustersWe investigate to what extent the spin axes of stars in young open clusters are aligned. Assuming that the spin vectors lie uniformly within a conical section, with an opening half-angle between {lambda}=0{deg} (perfectly aligned) and {lambda}=90{deg} (completely random), we describe a Monte Carlo modelling technique that returns a probability density for this opening angle given a set of measured sini values, where i is the unknown inclination angle between a stellar spin vector and the line of sight.2010MNRAS.402.1380Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/402/1380CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/320/74 : Radial velocities of Pleiades members (Mermilliod+ 1997)J/A+A/323/139 : K magnitude of Pleiades low-mass binaries (Bouvier+ 1997)J/A+A/335/183 : Pleiades low-mass stars rotational velocities (Queloz+ 1998)J/A+A/416/125 : RI photometry in {alpha} Per and Pleiades (Deacon+, 2004)J/A+A/488/409 : Radial velocities of {alpha} Per stars (Mermilliod+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/402/1380https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/402/1380http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/402/1380https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/402/1380https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/402/1380http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/402/1380GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/402/1380/table3 (*Estimated values of sini for stars in the Pleiades and {alpha} Per clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/1380/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/1380/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/1380/table3?GETtext/xml+votable180.050000true55.967291724.84161110.0055555555555555565/118 773 784 6/461 463 485 496 1726-1727 1742 1766 1769-1771 3140 31448.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/402/1380?format=asciiOpticaldefaultJ/MNRAS/402/1380/table3*Estimated values of sini for stars in the Pleiades and {alpha} Per clustersrecnoRecord number assigned by the VizieR team.
