Genetic links between IIIE iron meteorites and the core of the HED parent asteroid

Rocky planets formed through the differentiation of planetesimals into metal‑rich cores and silicate mantles, yet direct evidence linking these complementary reservoirs remains scarce. Here we show that IIIE irons and howardite-eucrite-diogenite (HED) meteorites are genetically l...
