Chondrules from high-velocity collisions: thermal histories and the agglomeration problem
Nick Choksi, Eugene Chiang, Harold C. Connolly +2
We assess whether chondrules, once-molten mm-sized spheres filling the oldest meteorites, could have formed from super-km/s collisions between planetesimals in the solar nebula. Hi…
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…
