Multi-Stage Core Formation in Planetesimals Revealed by Numerical Models and Hf-W Chronometry of Iron Meteorites
Abstract
The 182W content in IVB iron meteorites indicates metal separation at 2.9 Ma after CAIs. We calculated the differentiation of the IVB parent body comparing its evolution to the Hf-W model ages and provide a best fit on its radius and formation time.
