cds-question@unistra.frsolar-system-planetsIn this paper we present the guidelines for an extrasolar planet taxonomy. The discovery of an increasing number of extrasolar planets showing a vast variety of planetary parameters, such as Keplerian orbital elements, and environmental parameters, such as stellar masses, spectral types, and metallicity, prompts the development of a planetary taxonomy. In this work, via principal component analysis followed by hierarchical clustering analysis, we report the definition of five robust groups of planets. We also discuss the physical relevance of such analysis, which may provide a valid basis for disentangling the role of the several physical parameters involved in the processes of planet formation and subsequent evolution. For instance, we were able to divide the hot Jupiters into two main groups on the basis of their stellar masses and metallicities. Moreover, for some groups, we find strong correlations among metallicity, semimajor axis, and eccentricity. The implications of these findings are discussed.2007ApJ...666..475Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/666/475CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/666/475https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/666/475http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/666/475https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/666/475https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/666/475http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/666/475GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/666/475/table2 (Details on extrasolar planet clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/666/475/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/666/475/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/666/475/table2?GETtext/xml+votable180.050000true246.0053744-39.19298030.0055555555555555566/431 679 748 871 1597 2110 2472 3932 4136 4429 4528 5009 5522 5718 6219 6760 6791 6831 7240 7746 8357 9403 9459 9843 11087 11473 12030 12146 12465 12644 12899 12983 13702 14412 14416 14419 14434 14466 14527 14548 14914 15174 16213 16627 16652 17341 17496 17730 17954 18496 18614 18821 19904 19912 20145 21003 21838 21906 22036 22252 22590 22878 23013 23201 23681 24019 24178 25939 26183 26242 26575 26706 26978 26997 27018 27088 27164 27616 27750 27975 28130 28548 28763 28822 29513 29541 30015 30526 31374 31494 32561 32848 32930 33243 33377 33456 33630 33717 33923 34069 34905 34951 35079 35362 35442 35954 36697 37018 37246 37247 37461 37573 37954 37955 38545 38728 39257 39280 39364 39646 39675 40101 40442 40692 40985 41446 41607 41724 42044 42248 42333 42510 42760 43012 43228 43677 43813 43893 43911 44243 44398 44921 45168 45364 45865 46297 46306 46800 46967 47550 48105 48545https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/666/475?format=asciidefaultJ/ApJ/666/475/table2Details on extrasolar planet clustersClCluster identification (1)meta.codecharrecnoRecord number assigned by the VizieR team.
