Ordinary chondrites, the most common meteorites to reach Earth, consist of three subtypes: H, L, and LL chondrites, offering valuable insights into the solar system&#8217;s geochemical history. The Gefion Asteroid Family (GAF) has been proposed as a source for some L chondrites. In this study, we present the results of a spectroscopic campaign on dynamically defined members of the GAF, testing the hypothesis that L chondrites may originate from this family. Our new observations, combined with near-infrared (NIR) spectra from previous work, provide data for 18 asteroids. Compositional analysis reveals a range of meteorite analogs, including H (1 object, 6%), L (8 objects, 43%), and LL (1 object, 6%). Objects with L chondrite-like compositions were the most common in our sample. Accounting for uncertainties, we also observed intermediate subtypes, such as H\/L (5 objects, 28%) and L\/LL (3 objects, 17%). Based on these results, we conclude that the GAF is a viable source for some L chondrite meteorites. However, further investigations are needed to fully understand the family&#8217;s contribution to the broader meteorite population.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Allison McGraw, Vishnu Reddy, Juan A Sanchez Monthly Notices of the Royal Astronomical Society, Published: 24 January 2025 LINK + PDF (OPEN ACCESS) &#8220;Asteroid families provide critical clues to the nature of their original parent&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[77,23,7,337,130],"tags":[2932,4362,6809,3188,325,3257,1807],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/37291"}],"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=37291"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/37291\/revisions"}],"predecessor-version":[{"id":37292,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/37291\/revisions\/37292"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=37291"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=37291"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=37291"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
