cds-question@unistra.fropen-star-clustersstellar-spectral-typesastronomical-modelsvery-long-baseline-interferometryNearby young stellar moving groups have been identified by many research groups with different methods and criteria, giving rise to caution regarding the reality of some groups. We aim to utilize moving groups in an unbiased way to create a list of unambiguously recognizable moving groups and their members. For the analysis, two unsupervised machine-learning algorithms (K-means and Agglomerative Clustering) are applied to previously known bona fide members of nine moving groups from our previous study. As a result of this study, we recovered six previously known groups (AB Doradus, Argus, {beta} Pic, Carina, TWA and Volans-Carina). Three other known groups are recognized as well; however, they are combined into two new separate groups (ThOr+Columba and TucHor+Columba).2019MNRAS.489.2189Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/489/2189CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/489/2189https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/489/2189http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/489/2189https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/489/2189https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/489/2189http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/489/2189GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/489/2189/table2 (bona fide members of the newly defined groups)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/489/2189/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/489/2189/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/489/2189/table2?GETtext/xml+votable180.050000true4.587040130.95614650.0055555555555555566/46 102 462 601 666 674 719 765 784 826 940 1762 2374 2660 2671 2784 2966 3031 3210 3331 3799 5530 5718 6870 7760 10203 12417 12436 12770 13512 13674 14443 14640 15686 16393 16426 16455 16514 16543 16606 16853 16930 17242 17288 17552 17606 18636 18760 18797 19163 19382 19777 19782 19888 19948 20026 20129 20327 20381 20492 20505 20510 20591 20609-20610 20618 20636 20645 20647 20657 20701 20706 20996 21031 21050 21061 21082-21083 21090 21094 21118 21139 21146 21164 21199 21239 21296 21377 21386 21388 21420 21428 22066 22393 22619 22647 22683 22773 22857 22892-22893 22908 22942 22950 22964 22995 22999 23003 23005 23007 23014 23028-23029 23067 23136 23176 23388 23690 23715 23717 23731 23738 23740 23743 23895 24065-24066 24084 24086 24254 24314 24580 24608 24627 24629 24644 24716 24740 24763 25096 25113 26133 28746 28778 28784 28810 28929 29052 29168 29924 29999 30328 30613 30826 30951 31104 31505 32844 32847 32890-32891 32917 32930 32937 32970 33006 33065 33095 33100 33116 33129 33167 33186 33193 33312 33334 33349 33355 33361 33367 33374 33382 33422 33429 33446 33449 33456 33461 33464 33482 33500-33501 33512-33513 33517 33520 33523 33529 33548 33565 33583 33593-33594 33643 33654 33666-33667 33670 33689 33694 33697 33702 33704 33706-33707 33718 33737 33756 33850 33894 33919 33937 33956 33965 34008 34012 34054 34074 34102 34118 34126 34140 34146 34164 34196 34203 34206 34245 34338 34378 34380 34384-34385 34400 34406 34417 34423 34434 34436 34450 34464 34486 34509 34530 34538 34586 34607 34681 34699 34733 34742 34785 34790 34796 34819 34823 34825 34829-34830 34834 34840 34843 34857 34866 34880 34885-34886 34896 34909 34918 34930 34959 34961 34963 34998 35002 35027 35077 35112 35131 35202 35248 35268 35415 35497 35531 35640 35669 35696 35706 35814 35845 35859 35861 35885 35929 35945 36036 36129-36130 36146 36308 36322 36346 36487 36509 36543 36899 36907 36909 36969 37065 37085 37116 37248 37265-37266 37272 37285-37287 37289 37292-37293 37298 37300 37304 37307 37414 37419 37486 37489 37494 37574 37583 37637 37641 37647-37648 37652 37660 37664 37671 37678 37681 37683 37688 37690 37695 37703 37730 37745 37779 37781 37783 37785 37787-37788 37790 37792 37825 37838 37840 37844 38002 38341 38347 38359 38363 38382 38454 38489 38593 38687 38742 38797 38800 38936 38950 38985 38997 39002 39025 39123 39208 39310 39336 39524 39586 39829 41121 41139 41158 41295 41361 41553 41565 41681 41798 42096 42176 42242 42252 42374 43372 43670 43677 43704 44439 45072-45073 45120 45168 45238 45247 45324 45336 45345 45351 45378 45382 45389 45391 45394 45416 45453 45471-45472 45492 45503 45510 45538 45544 45576 45746 45770 45852 45876 45894 45927 45964 45967 45977 46082 46087 46094 46207 46339 46383 46529 46601 46615 46622 46629 46692 46922 46954 47120-47121 47125 47205 47207 47242 47249 47273 47345 47591 47610 47626 47652 47703 47777 47863 47911 47941 47943 47993 48038 48045 48061 48064 48124 48263 48274 48318 48325 48553 48559 48569 48643 48648 48651 48676 48684 48905 49135https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/489/2189?format=asciiRadiodefaultJ/MNRAS/489/2189/table2bona fide members of the newly defined groupsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
