OSIRIS-REx Returned a Pristine Sample of Asteroid Bennu: Takeaways from the Mission's Contamination Control and Knowledge Program
Jason P. Dworkin, Scott A. Sandford, Nicole G. Lunning +81
NASA's OSIRIS-REx mission had the objective of delivering a pristine sample from asteroid (101955) Bennu to Earth for scientific analysis--where "pristine" signifies the absence of…
Equilibrium Condensation from Chondritic Porous IDP Enriched Vapor: Implications for Mercury and Enstatite Chondrite Origins
Denton S. Ebel, Conel M. O'D. Alexander
The origin of Mercury's anomalous core and low FeO surface mineralogy are outstanding questions in planetary science. Mercury's composition may result from cosmochemical controls o…
Vapor-Melt Exchange -- Constraints on Chondrite Formation Conditions and Processes
Denton S. Ebel, Conel M. O'D. Alexander, Guy Libourel
The bulk volatile contents of chondritic meteorites provide clues to their origins. Matrix and chondrules carry differing abundances of moderately volatile elements, with chondrule…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
High Abundances of Presolar Grains and N-rich Organic Matter in CO3.0 Chondrite Dominion Range 08006
Larry R. Nittler, Conel M. O'D. Alexander, Jemma Davidson +3
NanoSIMS C-, N-, and O-isotopic mapping of matrix in CO3.0 chondrite Dominion Range (DOM) 08006 revealed it to have in its matrix the highest abundance of presolar O-rich grains (2…
The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites
Steven J. Desch, Anusha Kalyaan, Conel M. O'D. Alexander
We present a comprehensive evolutionary model of the Sun's protoplanetary disk, constructed to resolve the "CAI Storage" problem of meteoritics. We predict the abundances of calciu…
The Compositional Structure of the Asteroid Belt
Francesca E. DeMeo, Conel M. O'D. Alexander, Kevin J. Walsh +2
The past decade has brought major improvements in large-scale asteroid discovery and characterization with over half a million known asteroids and over 100,000 with some measuremen…
Cosmochemical Consequences of Particle Trajectories During FU Orionis Outbursts by the Early Sun
Alan P. Boss, Conel M. O'D. Alexander, Morris Podolak
The solar nebula is thought to have undergone a number of episodes of FU Orionis outbursts during its early evolution. We present here the first calculations of the trajectories of…
