cds-question@unistra.frsolar-system-planetsorbitsHabitable planets are likely to be broadly Earth-like in composition, mass, and size. Masses are likely to be within a factor of a few of the Earth's mass. Currently, we do not have sufficiently sensitive techniques to detect Earth-mass planets, except in rare circumstances. It is thus necessary to model the known exoplanetary systems. In particular, we need to establish whether Earth-mass planets could be present in the classical habitable zone (HZ) or whether the giant planets that we know to be present would have gravitationally ejected Earth-mass planets or prevented their formation. We have answered this question by applying computer models to the 152 exoplanetary systems known by 2006 April 18 that are sufficiently well characterized for our analysis. For systems in which there is a giant planet, inside the HZ, which must have arrived there by migration, there are two cases: (1) where the migration of the giant planet across the HZ has not ruled out the existence of Earth-mass planets in the HZ; and (2) where the migration has ruled out existence. For each case, we have determined the proportion of the systems that could contain habitable Earth-mass planets today, and the proportion for which this has been the case for at least the past 1000Myr (excluding any early heavy bombardment). For case 1 we get 60% and 50%, respectively, and for case 2 we get 7% and 7%, respectively.2006ApJ...649.1010Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/649/1010CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/649/1010https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/649/1010http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/649/1010https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/649/1010https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/649/1010http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/649/1010GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/649/1010/table1 (Habitability Outcomes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/649/1010/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/649/1010/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/649/1010/table1?GETtext/xml+votable180.050000true269.1479583-29.53922220.0055555555555555566/679 748 871 1597 2110 2312 2472 3932 4136 4429 4528 5009 5522 5718 6760 6791 6831 7240 7746 8357 8843 9403 9459 9843 11087 11473 12030 12146 12465 12644 12899 12983 14412 14416 14419 14466 14527 14548 14746 14914 15174 16213 16627 16652 17341 17496 17730 17954 18496 18614 18688 18821 19904 19912 20145 21003 21838 22036 22252 22518 22590 22878 23013 23030 23201 23681 24019 24178 25939 26183 26575 26706 26997 27018 27088 27164 27616 27750 27975 28130 28548 28763 28821 28822 29513 29541 30015 30526 31374 31494 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 40985 41446 41607 41724 42044 42248 42333 42510 42760 43012 43228 43677 43813 43818 43911 44243 44398 44921 45168 45364 45865 46297 46306 46800 46967 47550 48105 48545https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/649/1010?format=asciidefaultJ/ApJ/649/1010/table1Habitability OutcomesNameStar Namemeta.id.parentcharrecnoRecord number assigned by the VizieR team.
