cds-question@unistra.frmultiple-starssolar-system-planetsstellar-massesThe questions of how planets form and how common Earth-like planets are can be addressed by measuring the distribution of exoplanet masses and orbital periods. We report the occurrence rate of close-in planets (with orbital periods less than 50 days), based on precise Doppler measurements of 166 Sun-like stars. We measured increasing planet occurrence with decreasing planet mass (M). Extrapolation of a power-law mass distribution fitted to our measurements, df/dlogM=0.39M^-0.48^, predicts that 23% of stars harbor a close-in Earth-mass planet (ranging from 0.5 to 2.0 Earth masses). Theoretical models of planet formation predict a deficit of planets in the domain from 5 to 30 Earth masses and with orbital periods less than 50 days. This region of parameter space is in fact well populated, implying that such models need substantial revision.2010Sci...330..653Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Sci/330.653CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Sci/330.653https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Sci/330.653http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Sci/330.653https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Sci/330.653https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Sci/330.653http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Sci/330.653GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Sci/330.653/tables1 (G and K-type target stars in the Eta-Earth Survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Sci/330.653/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Sci/330.653/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Sci/330.653/tables1?GETtext/xml+votable180.050000true4.6744489-8.05300140.0055555555555555566/100 137 181 309 684 742 819 824 1098 1341 1530 1556 1642 2167 2622 3020 3102 3372 3509 3780 3979 4278 5009 5207 5304 5309 5522 5726 5824 5836 6226 6308 6409 6766 6926 6953 7745 8094 8887 9339 9403 9442 9476 9492 9662 9679 9801 9843 9873 10062 10598 10812 10899 11412 11633 11713 11806 12846 12856 12890 12944 13025 13301 13487 13568 13749 14278 14290 14419 14502 14539 15030 15154 15174 15221 16069 16274 16342 16689 17137 17266 17314 17425 17944 18115 18139 18614 18641 18821 19109 19327 19912 20145 20593 21185 21477 21484 21912 22708 22813 22818 23056 23096 23177 23583 24016 24028 24212 24558 24713 24777 24924 25102 25407 25880 25966 26183 26379 26575 26652 26906 27088 27954 28180 28400 28987 30343 30665 30878 31011 31029 31145 31433 31478 31545 31720 32318 32509 32561 32645 32757 36174 36288 36365 38807 40078 40242 40692 42845 43639 44262 44681 44879 46982 46997 47589 48652 48705 48964https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Sci/330.653?format=asciidefaultJ/other/Sci/330.653/tables1G and K-type target stars in the Eta-Earth SurveyrecnoRecord number assigned by the VizieR team.
