Has Dawn gone to the Wrong Asteroid? Oxygen Isotope Constraints on the Nature and Composition of the HED Parent Body
Abstract
Oxygen isotope analyses for 122 HED samples are used to examine whether Vesta is a viable source for the HEDs. The levels of isotopic heterogeneity within the HED parent body are assessed and the origin of anomalous HED meteorites re-examined.
