The method combines the \u03b1\u2013\u03b2 analytical formalism with a derivative-free global optimizer and a numerical inversion of the height\u2013velocity relation, enabling the retrieval of physically consistent solutions even when full velocity profiles are unavailable. Applied to the 2017\u20132018 European Fireball Network (EN) catalog, the approach achieves an 88% convergence rate when fitting only height\u2013velocity pairs, and 63% when terminal and initial masses are also imposed. 52% of mass-constrained solutions (34% overall) yield bulk densities consistent with their P E classes, with higher strength emerging as the primary discriminator among events retaining coherent classifications. Rapidly evolving high-energy, high-mass events show the largest incompatibility with the \u03b1\u2013\u03b2 model. The inversion produces a continuous bulk-density distribution spanning \u223c300\u20134000 kg m\u22123, in contrast to the discrete densities fixed by P E-based categories. The EN fireball dataset is now supplemented with self-consistent \u03b1 and \u03b2 estimates.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Eloy Pe\u00f1a-Asensio, Maria Gritsevich Icarus, In Press, Journal Pre-proof, Available online 5 May 2026 LINK + PDF (OPEN ACCESS) &#8220;Highlights &#8220;We present a three-point inverse solution for reconstructing meteoroid deceleration and mass-loss histories from sparse&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[96,97],"tags":[871,4467,881,1162,5205,4173,141,3711,3518,1141,2542],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/41596"}],"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=41596"}],"version-history":[{"count":2,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/41596\/revisions"}],"predecessor-version":[{"id":41598,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/41596\/revisions\/41598"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=41596"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=41596"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=41596"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
