Mixing Fraction of Inner Solar-System Material in Comet 81P/Wild2
Abstract
Using synchrotron-based x-ray microprobe measurements of the fraction of iron in sulfides and in crystalline materials in Stardust cometary samples, we estimate the fraction of inner nebular material in comet 81P/Wild 2 to be 0.6 ± 0.1.
