Here, we use N-body simulations to investigate the influence of giant-planet growth and inward type I migration on the delivery of outer Solar System bodies to the asteroid belt. We find that the radial distribution of planetesimals reflects that of the gas in the disk at the moment of implantation. Since chondrule-rich CM- and chondrule-poor CI-like bodies with diameters greater than 100\u2009km have different radial distributions, they must have been implanted at different times. CM-like bodies probably originate from the Saturn formation region and were implanted by aerodynamic drag into the belt during Saturn\u2019s growth phase, while CI- and comet-like bodies probably formed in the primordial trans-Uranian disk and were scattered inwards by the formation and migration of Uranus and Neptune driven by remaining planetesimals. Our results support a formation zone for chondrules interior to the ice giants (\u226410\u2009au), and suggest that CM-like bodies contributed to the water budget of the telluric planets.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sarah Anderson, Pierre Vernazza, Miroslav Bro\u017e Nature PREPRINT under review, Version 1, posted 28 May, 2024 LINK (OPEN ACCESS)PDF (OPEN ACCESS) Update (31 July 2025): PDF 2 (OPEN ACCESS) Update (8 September 2025): Nature Astronomy,&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9,10,18,72,127,73,81],"tags":[3273,5143,5007,105,3646,903,3152,5138,3873,3444,1855],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/36263"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=36263"}],"version-history":[{"count":4,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/36263\/revisions"}],"predecessor-version":[{"id":39065,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/36263\/revisions\/39065"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=36263"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=36263"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=36263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
