Fine-grained Material Associated with a Large Sulfide returned from Comet 81P/Wild 2
Zack Gainsforth, Andrew J. Westphal, Anna L. Butterworth +10
In a consortium analysis of a large particle captured from the coma of comet 81P/Wild 2 by the Stardust spacecraft, we report the discovery of a field of fine-grained material (FGM…
Measurement of the Oxidation state of Fe in the ISM using X-ray Absorption Spectroscopy
Andrew J. Westphal, Anna L. Butterworth, John A. Tomsick +1
The oxidation state of iron in the interstellar medium (ISM) can provide constraints on the processes that operated on material in the protosolar disk. We used synchrotron-based X-…
The Future of Stardust Science
A. J. Westphal, J. C. Bridges, D. E. Brownlee +13
Recent observations indicate that >99% of the small bodies in the Solar System reside in its outer reaches --- in the Kuiper Belt and Oort Cloud. Kuiper Belt bodies are probably th…
Oxygen Isotopic Composition of Coarse- and Fine-grained Material from Comet 81P/Wild 2
Ryan C. Ogliore, Kazuhide Nagashima, Gary R. Huss +3
Individual particles from comet 81P/Wild 2 collected by NASA's Stardust mission vary in size from small sub-m fragments found in the walls of the aerogel tracks, to large fragme…
Incorporation of a Late-forming Chondrule into Comet Wild 2
R. C. Ogliore, G. R. Huss, K. Nagashima +6
We report the petrology, O isotopic composition, and Al-Mg isotope systematics of a chondrule fragment from the Jupiter-family comet Wild 2, returned to Earth by NASA's Stardust mi…
Comparison of the Oxidation State of Fe in Comet 81P/Wild 2 and Chondritic-Porous Interplanetary Dust Particles
R. C. Ogliore, A. L. Butterworth, S. C. Fakra +3
The fragile structure of chondritic-porous interplanetary dust particles (CP- IDPs) and their minimal parent-body alteration have led researchers to believe these particles origina…
